Log Message:
Add ${BUILDLINK_LDFLAGS.dlcompat} (defined as "-ldl") to \ 
"LDFLAGS" under
Mac OS X. This is harmless under recent versions of Mac OS X where
"libdl.dylib" is symbolic link to "libSystem.dylib". And it \ 
is necessary
under old versions of Mac OS X (Jaguar and older) where we need the
"libdl.dylib" from the "dlcompat" package.

This should finally fix PR pkg/36086 by John D. Baker.
