So you're missing any reference to foo.so; not surprising it fails.
You need to make sure that "-lfoo" or something similar gets into the
link command for bar.so. You might still have some rpath issues after
that, but right now the runtime linker doesn't even know it should be
loading foo.so.

Oh, you're trying to build two separate shlibs in one Makefile? I don't
think that our Makefile infrastructure is smart enough to handle that,
at least not if cross-references are required. You'd probably be well
advised to split them into two separate source-code directories.
Another question worth asking yourself, if you are building like this,
is why you're bothering with two .so's at all. Is there a strong reason
not to just make them into one library?
