./configure options used for binary packges

[Skirmantas <skyjur@gmail.com>]

Hello,

I would like to see what options where used to "./configure" this binary 
package:
http://packages.debian.org/lenny/libapache2-mod-php5
(and some others)

I am trying to build php-5.3 from source and I would like to use those 
options as my base.

However I can't figure it out where to find them. Did I missed something?
