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 libglib.so because there's no reference for it in libpango.so. Work-arounds: 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...
