[Neurodebian-users] python package muddle

[Yaroslav Halchenko]

sorry about the delay... Michael reminded me about this outstanding
issue...

the reason is that you are trying to mix traits release 4.x
(python-traitsui) and 3.6 (python-traitsbackendwx):

$> acshow python-traitsui
Package: python-traitsui
Version: 4.1.0-1
Installed-Size: 4566
Maintainer: Debian Python Modules Team <python-modules-team at lists.alioth.debian.org>
Architecture: all
Replaces: python-traitsbackendqt, python-traitsbackendwx, python-traitsgui
Depends: python2.7 | python2.6, python (>= 2.6.6-7~), python (<< 2.8), python-traits, python-pyface, python-wxgtk2.8
Breaks: python-traitsbackendqt, python-traitsbackendwx, python-traitsgui
Description-en: traits-capable user interfaces
 The traitsui project contains a toolkit-independent GUI abstraction
 layer, which is used to support the "visualization" features of the
 Traits package. Thus, you can write code in terms of the Traits API
 (views, items, editors, etc.), and let traitsui and your selected
 toolkit and back-end take care of the details of displaying them.
Homepage: http://pypi.python.org/pypi/traitsui

$> acpolicy python-traitsbackendwx
python-traitsbackendwx:
  Installed: (none)
  Candidate: 3.6.0-3
  Version table:
     3.6.0-3 0
        900 http://debian.lcs.mit.edu/debian/ wheezy/main amd64 Packages
        600 http://debian.lcs.mit.edu/debian/ sid/main amd64 Packages

and /usr/share/doc/python-traitsui/changelog.Debian.gz would provide you
with a bit more details


and you see above in Breaks:  they conflict with each other.  You should be
good as far as you do not try pulling in 3.6.x series... or am I wrong?
