"undefined function: configure()" error post confi

After I go through the configuration I get a strange message... any help is appriciated.

*********
Don't forget to run this to make your Gallery secure!
Fatal error: Call to undefined function: configure() in /home/serenas/www/setup/write.inc on line 210
*********

It seems this is where normally you would get the bat or chmod instructions...

lines 209 and 210 in write.inc are

*********
echo _("Don't forget to run this to make your Gallery secure!");
configure("secure");
*********

I'm running
Gallery version: 1.4.3-RC1
Apache version: 1.3.27
PHP version: 4.3.3
OS: Redhat Linux 2.1AS
browser: mozilla 1.6b

TIA,
Rob
