[Bug 300008] [NEW] Missing link /usr/lib/wx/python/wx.pth

[Trevor King]

Public bug reported:

I was having trouble installing wx for python 2.5 on Hardy Heron.

1)
$ lsb_release -rd
Description:    Ubuntu 8.04.1
Release:        8.04

2)
$ apt-cache policy python-wxversion
python-wxversion:
  Installed: 2.8.7.1-0ubuntu3
  Candidate: 2.8.7.1-0ubuntu3
  Version table:
 *** 2.8.7.1-0ubuntu3 0
        500 http://us.archive.ubuntu.com hardy/universe Packages
        100 /var/lib/dpkg/status

I installed/uninstalled assorted wx related packages via aptitude, so it's possible the problem is due to another package and not python-wxversion.  After installation
  $ /usr/bin/python2.4
  >>> import wx
worked, but it failed in python 2.5
  $ python
  Python 2.5.2 (r252:60911, Jul 31 2008, 17:28:52) 
  [GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  >>> import wx
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ImportError: No module named wx

Trying to figure out why, I noticed a dead link:
  $ ls -l /usr/lib/python2.5/site-packages/wx.pth 
  lrwxrwxrwx 1 root root 22 2008-11-19 12:20 /usr/lib/python2.5/site-packages/wx.pth -> ../../wx/python/wx.pth
while the 2.4 link is
  $ ls -l /usr/lib/python2.4/site-packages/wx.pth 
  lrwxrwxrwx 1 root root 24 2008-11-19 12:20 /usr/lib/python2.4/site-packages/wx.pth -> /etc/alternatives/wx.pth
  $ ls -l /etc/alternatives/wx.pth
  lrwxrwxrwx 1 root root 28 2008-11-19 12:23 /etc/alternatives/wx.pth -> /usr/lib/wx/python/wx2.8.pth
and wx2.8.pth is a real file (contents: wx-2.8-gtk2-unicode)

Solution:
Whichever package (presumably python-wxversion) sets these links up needs to redirect the 2.5 wx.pth to '/etc/alternatives/wx.pth'.
