pgsql error - situation update

My sysadmin just called and tol me he updated the php.rpm... he happens to
be in California totally
across the US from me for a week...
So I check the ver and...

Php version 4.1.2-7.2.6 recently updated - yesterday
Postgresql 7.3.3 installed in august sometime - upgraded from basic redhat
7.2 postgresql

Since he upgraded the php rpm this problem started.

Fatal error: Call to undefined function: pg_connect() in
/var/www/html/crohns/phpBB2/db/postgres7.php on line 79

in website address

So you maybe right on recompiling and if so...how do I go about that
