I can't get PostgreSQL to work

[vasah20]

I can't get Import pg to work correctly.
I'm running python 2.1 on Linux-mandrake 8.0

bash> python
>>> import pg
Traceback (most recent call last):
File &quot;<stdin>&quot;, line 1, in ?
File &quot;/usr/local/lib/python2.1/pg.py&quot;, line 7, in ?
from _pg import *
ImportError: libpq.so.2: cannot load shared object file: No such file or directory
>>>

bash>find / -iname 'pg.py'
/usr/local/lib/python2.1/pg.py

TIA
