Thread:Talk:MediaWiki/Install failed on CentOS 5.3/reply (2)

I have exactly this problem. I have tried the hack of Installer.php as suggested by an article in this discussion group but to no avail.

Is this something to do with it?

"If you are installing MediaWiki on CentOS 5.6, use the php53 package instead of php. The php package contains PHP 5.1.x, which is not compatible with the latest version of MediaWiki."

I do not know what the php53 package is.
