Solaris 10, mod_auth_pgsql2

Greetings.

I'm trying to compile mod_auth_pgsql2 for Solaris 10, I have the
blastwave packages installed for libpq, apache2 and apache2_devel

I'm following this how to

http://archives.postgresql.org/pgsql-performance/2007-10/msg00076.php

However, when I run it i get this

sandbox# /opt/csw/apache2/sbin/apxs -i -a -c -l /opt/csw/postgresql/
include -L /opt/csw/postgresql/lib -lpq mod_auth_pgsql.c

cc: acomp failed for mod_auth_pgsql.c
apxs:Error: Command failed with rc=65536

Now the strange thing is this

sandbox# ls -l /opt/csw/postgresql/include/libpq-fe.h
-rw-r--r-- 1 root bin 17983 Feb 16 2007 /opt/csw/
postgresql/include/libpq-fe.h

I'm not that great with compiling and whatnot, so I'm at a bit of a
loss.

Advice ?

Thanks.
