I'm assuming that you mean the *module* is an extension library (i.e. a
.so file that is imported by your python code) and the *library* is
another .so that is needed by that module. In this case, the module must
be in the PYTHONPATH just as I mentioned, but the library must be in
your machine dynamic linker path. Take a look at the ld.so man page
("man ld.so") and, if your machine runs Linux, at the file
/etc/ld.so.conf and the ldconfig man page ("man ldconfig"). You may need
to configure the LD_LIBRARY_PATH environment variable.
