[Zope] Error starting zope - undefined symbol: PyUnicodeUCS2_AsEncodedString

[John Schinnerer]

Apologies, forgot to paste in the full traceback, here it is.
FWIW I also have zope 2.9.7 installed from source and working just fine 
on this same machine (using python 2.4.4 packaged with Etch).

Traceback (most recent call last):
