Effective with the new release of matplotlib 1.5.0, support for Python 3.3 has been dropped. See https://mail.python.org/pipermail/matplotlib-announce/2015-October/000003.html where it is stated "In 1.5.0 we have dropped official support for python 2.6 and 3.3." This should be reflected in ebuild python compatibility, e.g.: 7c7 < PYTHON_COMPAT=( python2_7 python3_{3,4,5} ) --- > PYTHON_COMPAT=( python2_7 python3_{4,5} ) I can't confirm this causes any problems right now as I don't use python 3.3, but it is bound to cause problems at some point as python 3.3 is no longer tested for correct behavior in their continuous integration. Reproducible: Didn't try
Thanks for reporting. We will drop support here as soon as we are dropping py3.3 from reverse deps of matplotlib. Otherwise we will break lot's of packages. So far testsuite runs fine for py3.3
py3.3 support has been dropped from Gentoo.
