PHP5 as apache module using packages

[Gary Hartl]

Hi all;

Ok so i've reinstalled fBSD-7 and i'm running apache 2.2 installed using
pkg_add

I need to also run php as a module for apache (the web software i'm using
requires php as module no cgi).

Now I pkg_add'ed php5 from sparc64/all tree on ftp.freebsd.org, 

I think I missed passing a variable throu to php.  

My question is how do I know what variables I can pass throu to a package to
adjust its installation.

Thanks 

Gary
