Post the result of:

echo "<?php echo phpinfo(); ?>" | php

I'm trying to install wikidot in a Centos 5 server.

I have installed PHP 5.2, Postgresql 8.3, got the wikidot clone from github.

Whenever I try to run the 'make prepare_db' as postgres user I got the following error:

Fatal error: Call to undefined function pg_escape_string()

If I try to execute 'make' I get:

Call to undefined function pg_connect()

I have the following libraries installed:

Is there anything else I need to install to be able to execute the Makefile on wikidot?

Thanks,
