Forum OpenACS Q&A: PostgreSQL Driver installation problem

Since I couldn't get the RPMs working, I tried to install OpenACS
using source code. Now, I've got a problem with installing PostgreSQL
driver. I've downloaded the tarball, and changed the Makefile a little
and when I 'make' it gives me this error:

gcc -DFOR_ACS_USE -DBIND_EMULATION -I/home/aolserver/include
-I/usr/include/postgresql
-I/home/aolserver/include -D_REENTRANT=1 -DNDEBUG=1 -g -fPIC -Wall
-Wno-unused -mcpu=i686 -DHAVE_CMMSG=1 -DUSE_FIONREAD=1
-DHAVE_COND_EINTR=1   -c -o postgres.o postgres.c
postgres.c:45: libpq-fe.h: No such file or directory
make: *** [postgres.o] Error 1

This file that they are talking about(libpq-fe.h) is located at 
/usr/local/pgsql/include.

This is my makefile:

# Copyright 1994-1996 America Online, Inc.

#
# Makefile for postgres.so module.
#
# -DFOR_ACS_USE required for OpenACS use!

# To have the AOLserver load the postgres.so module at runtime, you will
need
# to add the following entry in the [nsservergodzillamodules] section
of your
# nsd.ini file (where 'godzilla' is the name of a virtual server):
#
#
postgres=postgres.so

My aolserver is located in '/home/aolserver' and my postgres is
located at '/usr/local/pgsql'.

There was a similar posting for this problem a while back, and
apparently commented something out did the trick. Could someone please
tell me what's wrong.

Thanks.
