I'm about to commit matplotlib-0.84 to the tree with added dependencies on dev-python/pytz and dev-python/python-dateutil. I've dropped the ~ppc and ~amd64 keyword from matplotlib because the new deps aren't keyworded yet. Please test and keyword the new dependencies and matplotlib (pytz and python-dateutil have test suites ran by FEATURES=test, if installed with USE=doc matplotlib installs /usr/share/doc/matplotlib-0.84/examples/date_demo2.py that uses the new deps). (I hope I got this bug right, first time I do this)
amd64 done
ppc done
