undefined symbol: PyUnicodeUCS4_FromUnicode

[Bill Hodges]

I just build PyQt from sources on Mandrake 10 and tried to run
a le gacy application from a University that
runs in several environments. I detectedno errors on the
configuration or build and the qt.so is the same in the build directory 
as it is in the site-packages/qt.so.

output is:

psyco installed and used
Traceback (most recent call last):
   File "/usr/local/lib/python2.3/site-packages/drt/drt.py", line 40, in ?
     from qt import *
ImportError: /usr/lib/python2.3/site-packages/qt.so: undefined symbol: 
PyUnicodeUCS4_FromUnicode

Any pointers on how to resolve?
