$ ./parrot examples/opengl/shapes.pir
Could not find a suitable GL shared library!

This is after OpenGL is detected by Configure.pl :

Hello, I'm Configure. My job is to poke and prod your system to figure out
how to build Parrot. The process is completely automated, unless you passed in
the `--ask' flag on the command line, in which case I'll prompt you for a few
pieces of info.

Since you're running this program, you obviously have Perl 5--I'll be pulling
some defaults from its configuration.

init::manifest - Check MANIFEST.....................................done.
init::defaults - Set Configure's default values.....................done.
init::install - Set up installation paths..........................done.
init::hints - Load platform and local hints files................done.
init::headers - Find header files distributed with Parrot..........done.
inter::progs - Determine what C compiler and linker to use........done.
inter::make - Is make installed...................................yes.
inter::lex - Is lex installed................................skipped.
inter::yacc - Is yacc installed...............................skipped.
auto::gcc - Is your C compiler actually gcc................yes, 4.0.
auto::glibc - Is GNU libc installed................................no.
auto::backtrace - Does libc have the backtrace* functions.............yes.
auto::msvc - Is your C compiler actually Visual C++..........skipped.
auto::attributes - Detect compiler attributes.........................done.
auto::warnings - Detect supported compiler warnings..........set for gcc.
init::optimize - Enable optimization..................................no.
inter::shlibs - Determine flags for building shared libraries......done.
inter::libparrot - Should parrot link against a shared library.........yes.
inter::charset - Which charset files should be compiled in..........done.
inter::encoding - Which encoding files should be compiled in.........done.
inter::types - What types should Parrot use.......................done.
auto::ops - Which opcode files should be compiled in...........done.
auto::pmc - Which pmc files should be compiled in..............done.
auto::alignptrs - Determine your minimum pointer alignment........ 1 byte.
auto::headers - Probe for C headers................................done.
auto::sizes - Determine some sizes...............................done.
auto::byteorder - Compute native byteorder for wordsize.....little-endian.
auto::va_ptr - Test the type of va_ptr...........................stack.
auto::format - What formats should be used for sprintf............done.
auto::isreg - Does your C library have a working S_ISREG..........yes.
auto::arch - Determine CPU architecture and OS..................done.
auto::jit - Determine JIT capability.............................no.
auto::cpu - Generate CPU specific stuff........................done.
auto::funcptr - Does compiler support function pointer casts.......done.
auto::cgoto - Does your compiler support computed goto............yes.
auto::inline - Does your compiler support inline...................yes.
auto::gc - Determine allocator to use.........................done.
auto::memalign - Does your C library support memalign........already set.
auto::signal - Determine some signal stuff........................done.
auto::socklen_t - Determine whether there is socklen_t................yes.
auto::neg_0 - Determine whether negative zero can be printed......yes.
auto::env - Does your C library have setenv / unsetenv.........both.
auto::thread - Does your system has thread.........................yes.
auto::gmp - Does your platform support GMP......................yes.
auto::readline - Does your platform support readline.................yes.
auto::gdbm - Does your platform support gdbm....................done.
auto::pcre - Does your platform support pcre................yes, 7.7.
auto::opengl - Does your platform support OpenGL....yes, MacOSX_GLUT 5.
auto::crypto - Does your platform support crypto...........yes, 0.9.8h.
auto::gettext - Does your configuration include gettext.............yes.
auto::snprintf - Test snprintf......................................done.
auto::perldoc - Is perldoc installed................................yes.
auto::pod2man - Is pod2man installed................................yes.
auto::ctags - Is (exuberant) ctags installed......................yes.
auto::revision - Determine Parrot's revision......................r40554.
auto::icu - Is ICU installed....................................yes.
gen::config_h - Generate C headers.................................done.
gen::core_pmcs - Generate core pmc list.............................done.
gen::crypto - Generate Digest PMC files..........................done.
gen::parrot_include - Generate runtime/parrot/include....................done.
gen::opengl - Generating OpenGL bindings.........................done.
gen::call_list - Generate NCI signature list........................done.
gen::makefiles - Generate makefiles and other build files...........done.
gen::platform - Move platform files into place.....................done.
gen::config_pm - Record configuration data for later retrieval......done.
Okay, we're done!

You can now use `gmake' to build your Parrot.
After that, you can use `gmake test' to run the test suite.

Happy Hacking,
