Yes, this is a problem with .dylibs on the mac. As far as I know [someone
correct me if I'm wrong], there are two ways to 'fix' this:

1) Use the 'install_name_tool' to post-process the shared libs with the
correct path

2) Add the environment variable DYLD_LIBRARY_PATH or the safer but hardly
documented DYLD_FALLBACK_LIBRARY_PATH
