Updating executables in mac bin directory.

Updating mac bin with universal (compiled for archs ppc, i386, and
x86_64) statically-linked binaries built under Darwin 8.11.1 on a mac
running osx 10.4.11 (montgomery). This will (hopefully) work on most
macs. However, while GSL is statically linked, `libSystem.B.dylib` is
still dynamically linked.
