[Zope] ZOPE and ActivePython

I have recently installed ZOPE 2.5 and before that i had installed ActivePython 2.2 , but at zope info page it is like that: Zope Version (Zope 2.5.0 (binary release, python 2.1, win32-x86), python 2.1.2, win32) Python Version 2.1.2 (#31, Jan 15 2002, 17:28:11) [MSC 32 bit (Intel)] System Platform win32 And then , can't i compile zope with ActivePython , or can't i compile extensions to zope using the active state version? I want explanations with that , for i'm very confused here , don't know what to do...
