Probleme a l'installe d'un paquet debian

Bonjour,

Je viens de backporter wxWindows 2.4 pour woody, et lors de l'installe du
paquet wxPython, voici ce que j'obtiens:

# apt-get install -f
Reading Package Lists... Done

Setting up libwxgtk2.4-python2.2 (2.4.1.2) ...
warning: local name 'self' in '__init__' shadows use of 'self' as global in
nested scope 'lambda'
Sorry: AssertionError: SRE module mismatch
dpkg: error processing libwxgtk2.4-python2.2 (--configure):
subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
libwxgtk2.4-python2.2
E: Sub-process /usr/bin/dpkg returned an error code (1)

Il y a visiblemnt un petit truc a changer (qui passe sur sid et pas sur
woody), mais je ne sais pas ou chercher. Comment savoir ou est le probleme ?
Ou est le script de post-install ?

Merci.
