If you make a page with
, you should see a section with "Configure Command" in it (it's near the top). Look in the grey box, do you see '--with-mysql=/path/to/mysql'? If not, then I
think you'll have to rebuild PHP to include support for MySQL (edit: unless you can find an RPM for PHP 5 that's built with it). Unfortunately it isn't enabled by default in PHP 5 (but I guess you've seen
this already)
. HTH.
