This bug was fixed in the package model-builder - 0.4.1-2ubuntu1

---------------
model-builder (0.4.1-2ubuntu1) hardy; urgency=low

  * Resync with Debian unstable.
  * debian/control:
    - Let model-builder binary package depend on python-wxgtk2.6 to fix
      VersionError exception (LP: #146182).
    - Update Maintainer field as per spec.

model-builder (0.4.1-2) unstable; urgency=low

  * debian/control: Build-Depend and Depend on python-numpy instead of
    python-numpy-ext and python-numpy-dev virtual packages provided by
    python-numpy (Closes: #463208)

model-builder (0.4.1-1) unstable; urgency=low

  * New upstream release
  * Bump Standards-Version to 3.7.3

This bug seems to have returned in 0.4.1-4. I have just installed it and I get the same error message as originally reported. Installing python-wxgtk2.6 fixes the problem.

This bug is still present. Just tested with freshly-installed model-builder package on Intrepid. output:

[George (gnwiii)]

Ubuntu 9.10 Matplotlib requires wxPython 2.8, but model-builder still requires wxPython 2.6

  File "/usr/lib/pymodules/python2.6/matplotlib/backends/backend_wx.py", line 144, in <module>
    raise ImportError(missingwx)
ImportError: Matplotlib backend_wx and backend_wxagg require wxPython >=2.8

Workaround: remove wxPython 2.6, install python-setuptools and use easy_install to install
Model_Builder:

PYTHONPATH=/usr/local/lib/python2.6/site-packages easy_install-2.6 -d /usr/local/lib/python2.6/site-packages/ Model_Builder
