Dynamic linker error messages are notoriously unhelpful :-(.  I'll bet
it's really complaining about not being able to find some library that
libpq.so depends on.  You should be able to use ldd (or local equivalent)
to inspect the list of libraries that libpq.so needs, and from there
figure out what the problem is.
