In portage, dev-python/traits (4.5.0, our only current version) is marked as only python 2.7 compatible. The package has been python 3 compatible for a while now, as the changelog (from the downloadable archive, here https://pypi.python.org/pypi/traits ) explicitly states. I have also installed the package manually on a few systems using python 3.4 and I can confirm it works. A number of other packages which are python 3.4 compatible (e.g. sci-libs/nipype, which I maintain) are dependent on traits, and traits is the only dependency that prevents marking them as python 3.4 compatible. Could you please fix this?
