On OS X there is a difference between bundles loadable at runtime
(foo.so) and dynamic libraries used at link time (foo.dylib). They
are build with different linker flags. This creates the problem what
libR.dylib is, precisely, because obviously it is a module that must
be loaded into perl at runtime. Your perl does find libR.dylib, but
it cannot find the symbols it needs in there (it seems). Since this
will be a problem for all of the "bi-directional" OmegaHat packages, I
think
it must be resolved in a general way by the OmegaHat team.
