 I have a standard Debian squeeze installation as a buildbot slave with:
 {{{
 Buildbot version: 0.7.12
 Twisted version: 10.1.0
 Python 2.6.6
 }}}
 and running 0.8.7p1 as a buildbot server.

 The build fails with the following trace:
 {{{

 I'm puzzled about python2.7 directory name and whether it is buildbot bug
 with Python versions or backward compatibility issue. It would be nice if
 backward compatibility was properly documented.
