The problem is that IBM's linker has some "odd" ideas about cross-library
calls.  Basically, what happens is that libtool is linking pango without
a -lglib flag, and a -berok flag to accept errors.  At runtime, shared lib
linking for pango doesn't resolve anything in because there's
no reference for it in


1) Fix libtool to not pass -berok and then make sure all the needed -lwhatever
are specified at each step.  Yes, you'll end up with very long -l lists once
you get to gtk+.

2) Use the '-blazy' and/or '-lrtl' flags to do lazy-loading of shared objects.
This works, but then you have to specify -lrtl for all programs that use the
libraries.  Also, the man page warns ' Programs that depend upon the comparison
of function pointers should not use lazy loading.' because different modules
can get different values for the same function pointer.

Hope this helps...
