[gentoo-python] twisted-r1.eclass postrm failure for new twisted ebuilds

[Brian Dolbec]

OK, I've got the new twisted ebuild almost ready.  I have the tests
working, only diabling the network test group and one other that was
disabled in the split pkg ebuild.

But, the twisted-r1 postrm function is not working correctly.  I have
been overriding it in the ebuild so far.  It seems that there is an
EPYTHON issue...

I'll let the traceback speak for itself.

 * python2_7: running distutils-r1_run_phase twisted-r1_update_plugin_cache
 * python3_4: running distutils-r1_run_phase twisted-r1_update_plugin_cache
Traceback (most recent call last):

ImportError: This package should not be accessible on Python 3. 
Either you are trying to run from the python-future src folder or your installation
 of python-future is corrupted.



What I can't figure out is of it isn't EPYTHON that is screwed up, how the hell is 
this happening...  a simple py3.4 import re causes the 3.4 re.py to try and import a 
py2.7 version of copyreq.

I can't reproduce this in a terminal window with py3.4 session.  "import re" is fine and
works correctly.  So, it can't be a bad python install.

I'll work on pushing the changes to the twisted ebuilds in the morning to my buildbot-dev overlay.
But I have attached the WIP ebuild for 16.3.0.  You can grab the files dir from [1] if you want 
to try emerging it.
