[PEAK] setuptools: Test works only after second invocation

[Nikolaus Rath]

Hello,

Can someone explain to me what's going on here?

First invocation:

$ ./setup.py test
running test

Further calls to test work just fine -- until I delete the unittest2
folder in the current directory.

I have put a testcase on http://www.rath.org/trouble.tar.bz2. Note that
this only works if the unittest2 package is *not* installed.




Thanks,

   -Nikolaus
