Hi,

I'm working on python-ruffus (current work not commited to Git since
upstream is preparing a new version - I'm fine to inject Beta to Git if
the abstract description of the problem is not sufficient).  Upstream
said it works with tox and thus I tried in debian/rules:


export PYBUILD_TEST_TOX=1

%:
	dh $@ --with python2,python3,sphinxdoc --buildsystem=pybuild


which resulted in:

...
   dh_auto_test -O--buildsystem=pybuild

The following lines look suspicious to me:

  cmdargs=['/usr/bin/python3', '-mvirtualenv', '--setuptools', '--python', '/usr/bin/python2.7', 'py27']
  ...
  Downloading/unpacking setuptools
  Downloading/unpacking pip


For the record: After noticing this "Downloading/unpacking" I added
python-setuptools + python-pip to the Build-Depends with no change.

If there is no simple answer to this problem I can commit my current
code to git://anonscm.debian.org/debian-med/python-ruffus.git.

Any help is welcome

      Andreas.
