Thats not my problem. The Problem is that i cant install the same port on
python2.4 and python2.5 (py-MySQLdb and py-ldap that zope needs and other
applications need it under python2.5)

shouldn't the already installed test be aware that py24- and py25- can be
installed at the same time.

It works without problem. I just have to force the installation so
portupgrade doesn't work for these ports properly
