Hello Julien, thanks for the bug reporting, that’s helpful.

A few tips for better bug reports:
1) Setting the “Distutils2” component will automatically add Tarek and I to nosy, you don’t have to do it manually (especially when you find an obsolete user name for Tarek).
2) The “Versions” field is used to manage CPython releases; given that d2 is not in the CPython tree, the right value here is always 3rd party”.  Including the OS and Python version in your report text is useful, though.  We want to support 2.4-2.7 in d2 (and 3.x Really Soon Now™).
3) Always try to reproduce the bug with the latest version from bitbucket.org/tarek/distutils2

I borrowed the time machine and fixed that bug in 82c9a472e8b8, six days ago.  :)
