Further investigation reveals that this pr is substantially in error.

If I set LTDL_LIBRARY_PATH=${LOCALBASE}/lib when building g-wrwap,
it appears to load the .dylib files without problem.  Additionally,
symlinking the .dylib files to the expected .so names does not fix the
problem.

I will close this pr and possibly open a new pr against devel/g-wrap
about setting the LTDL_LIBRARY_PATH variable so it can find the
module it is attempting to load.
