When I try to run a jruby app it cannot locate libc.dyld

I originally left details here : boxen/puppet-ruby#14 (comment)

Essentially it seems the java shim sets $DYLD_FALLBACK_LIBRARY_PATH to help find homebrew libs, but it my experience it means it cannot find the libs in /usr/local.

I can manually export DYLD_LIBRARY_PATH=/usr/lib and then jruby finds libc again, but as noted in the other thread - there are some weird osx issues if setting a DYLD env variable.

Before using boxen I didn't seem to have any issue with jruby finding gcc installed through homebrew, but I sure there's a reason for the shim setting the DYLD path.

For now I've removed the shim from the path so that it falls back to /usr/bin/java and haven't noticed any side-effects yet.

Thoughts - ideas?

Thanks
