PHP MySQL extensions problem

[Jose Borquez]

I am attempting to configure Group Office and every time I go to the 
site I get the following error:
*
Fatal error:* The required PHP MySQL extension is not installed.Please 
take a look at http://www.php.net for more information about installing 
this extension

I did a pkg_info and it says I have php5-extensions-1.0 installed.  I 
even uninstalled them and installed them again with no luck.  I went to 
the php.net website, but found nothing on this problem.

Could someone please give me any pointers as to what I can do to resolve 
this?

Thank you in advance,
Jose
