[Zope] volunteer or help for volunteering

Hi There is this great zope installer for Zope 2.4.3 for MacOSX including the Zope controller on: http://www.zope.org/Members/richard/zope_for_osx/ As I learned, we don't have one for Zope 2.5. I would love to make one if someone told me how (I have the developer tools). Can anybody help? Thanks a lot Uwe
