I can't tell from the trace back if you have activated or not. I also
would not clone the repo into the venv.
If the source for mpl is in `~/source/matplotlib` :
pyvenv --system-site-packages /tmp/test
source /tmp/test/bin/activate
cd ~/source/matplotlib
python setup.py develop
Should install matplotlib into the 'test' venv (which lives in RAM on most
modern linux machines).
