[GRASSLIST:7885] db.connect problem

I'm running GRASS 6 on Linux and trying to connect to a PostgreSQL 
server and connot; I get this error:

db.describe table=location driver=pg 
/awips/rep/lx/local_apps/grass6-build/grass-6.0.0/driver/db/pg: error 
while loading shared libraries: libpq.so.3: cannot open shared object 
file: No such file or directory
dbmi: Protocol error (invalid table/column name or unsupported column type)

GRASS_INFO_ERROR(13033,1): No db connection for driver <pg> defined. Run 

I did run db.connect, both before & after running db.describe (which I 
used to test whether or not I was really connected), but there was never 
any indication that I had established a connection to PostgreSQL.

I do have PostgreSQL installed and when I compiled GRASS I did not have 
any errors or indications that there were any problems linking with the 
PostgreSQL libs. I assume libpq.so.3 should be in the GRASS6 lib 
directory (it surely is not). I'm at a loss what steps I should take 
next since the build seemed to be fine. The configure files show the 
appropriate locations of the pgsql includes and libs.
