[Zope] Help! Can't restart Zope! (escalated from: Python switcheroo)

[Robert Rottermann]

you have to reinstall Zope after you have changed your Python, since the 
  correct libraries and their location must be known at compile time.

Go to your Zope source directory
execute the following commands:
- make clean
- make
- make install

Be careful to store away your Data.fs before doing this.
Nothing should happen to it but "Vorsicht ist die Mutter der 
Porzelankiste"  we say in German.
