I've never installed it on linux, but I have messed about with PgSQL a 
fair amount. I also am not certain sure this is going to help. But your 
plea was desperate, so...

I am guessing that your libpq (the PostgreSQL C client library) is 
missing or corrupted. I would try following:  make sure that 
/usr/local/pgsql/bin/pg_config exists, and run it to find out where it 
thinks it's libraries should live:

# /usr/local/pgsql/bin/pg_config --libdir
(output = /usr/local/pgsql/lib, or maybe somewhere else on linux?)

See what's in /usr/local/pgsql/lib (you should have libpq in there)

On Linux, you can run "ldconfig -v" to see your current libraries 
configuration. If libpq is not in that listing (ldconfig -v | grep pq) 
then you need to edit ldconfig.conf (sp?) and rerun ldconfig -v to make 
sure it's picking it up.
