[Zope] Zope.org Python & Python.org Python

Hello all, I was wondering if it's possible for me to use the instance of Python 2.1.3 created by the installer instead of Python that comes with Zope? I.e., in z2.py, change c:\zope-dir\python\python.exe c:\zope-dir\zope\z2.py ... other args ... to - c:\python213-dir\python.exe c:\zope-dir\zope\z2.py ... other args ... Are there differences between the way Python is compiled in the 2 instances? I'm on Win32. TIA. Regards, Samir
