Import error using pyPgSQL

Hi Folks-
I know there's probably an easy answer to this question but it's not
coming to me so I thought I'd ask for help.  I think I've successfully
built and installed the pyPgSQL module and I know for sure libpq is
installed and working because I've used it in a small C program
interfacing with my PostgreSQL database.  However, in my Python code,
the line "from pyPgSQL import PgSQL" causes an error "ImportError:
/usr/lib/python2.3/site-packages/pyPgSQL/libpq/libpqmodule.so: undefined
symbol: lo_export".  

Any ideas?  This is on a PC running Linux Fedora Core 2, Python 2.3 and
PostgreSQL 7.3.4.  I can always call the C program from Python and that
works fairly well but at this point I'm exploring options.  Plus, to be
honest, it's a little annoying that one way works and the other doesn't
so now I'm curious as to why.  Any help, thoughts or suggestions would
be greatly welcomed.
