Apparently the python2 variant of this package requires
"python2-subprocess32". Could you look into packaging it?

It also requires "python2-functools32", but this dependency is removed
again in the matplotlib master branch. I have this in my local branch.

I found these dependencies by building dependent packages. Too bad the
setup script only prints a warning if they are not found, instead of
failing.
