be more strict about matching available version numbers
clone with depth 1 when installing deps from git
more quoting
move more code into util.bash and handle running without init/perlbrew better
remove some debug code
maintain existing cpan configuration where possible
allow comments and ! prefixed (non-prebuilt) local::libs
on ancient perl, reconfigure cpan before and after installs

work around quoting issues with 5.20
cleaner build flag testing
local-lib testing
test prebuilt downloading
revise perls to test
ensure we clone repos as single branches
test git installation
more consistency in function names
fix local-lib test
move toolchain module list to local-libs.txt
