libpq.so.2 problems

Hi,
I'm having trouble with libpg.so.2.
Specifically:

Can't load '/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/auto/
Pg/Pg.so' for module Pg: libpq.so.2: cannot open shared object file: No
such file or directory at /usr/lib/perl5/5.8.0/i386-linux-thread-multi/
DynaLoader.pm line 229.

I noticed someone else was having simlar trouble o nthe 11th of June.

libpq.so.2 does exist, but is in:
/usr/lib/pgsql/backup/libpq.so.2
the permission set on this directory (and the name) suggest that things
in here shouldn't be used.
Whats the score? should i just copy libpq.so.2 back out to /usr/lib
along with all the other libpq.so.X's ?

I have upto date versions of BDI::Pg, Pg, and
postgresql-libs-7.3.2-3.i386.rpm (Redhat 9).

Thanks.
