Hmm, I just bounced to emails.  Do we have to use the web interface?  Anyhow, I've reproduced the bug in a script:

It took me a bit of digging through my aptitude logs before I could too,
so I'm not supprised ;).  Sorry I didn't think to check them earlier :p.

That's what I get after a good install, see screenlog.0 below.

I don't remember, but that's ok, reproduction below.

No.  Only Ubuntu packages for wxwidgets.


After digging through my aptitdue logs, I see that I was a bit
confused.  I think I was trying to get `import wxWidgets' working in
python to get some old code going, not realizing that it should have
been `import wx'.  Anyhow, a script reproducing my bug and a
screendump of it's output are attached.

The 2.4 install step somehow mangles the linking situation, setting up

ls: cannot access /usr/lib/wx/python/wx.pth: No such file or directory
/etc/alternatives/wx.pth -> /usr/lib/wx/python/wx2.8.pth
/usr/lib/python2.4/site-packages/wx.pth -> /etc/alternatives/wx.pth
/usr/lib/python2.5/site-packages/wx.pth -> ../../wx/python/wx.pth

Which persists through the remainder of the broken approach.  A full
clear and reinstall without any 2.4 packages fixes the situation.

Hope that helps :)
Trevor
