Over 300 test failures for `=dev-python/colorcet-2.0.6`

This is the full build log. Most issues seem to be AssertionErrors.

From the log it looks like this is reporting issues with gentoo, not with the colorcet library as packaged by the colorcet authors? If so I don't think that this repo is the place to report such issues; presumably take that up with wherever that build is being done.

@jbednar I think @TheChymera works on distributing packages for Gentoo and is reporting that the colorcet test suite does not run correctly on their build system. The errors seems real and not Gentoo specific e.g.:

k = 'linear_grey_10_95_c0_r', v = <matplotlib.colors.LinearSegmentedColormap object at 0x7f6d98b6a980>

    def test_get_cm(k, v):
        import matplotlib.cm as mcm

@TheChymera , can you check whether this would resolve your issue? If so, I can make a new patch release of colorcet, but this is the only user-visible change since the previous release, so I'd like to know it's actually going to help!
