@GrahamcOfBorg build pythonPackages.mox3 python3Packages.mox3

The test requirements don't look too weird - could we probably just add them to checkInputs and keep running tests?

The problem is the test dependencies are not packaged in nixpkgs, therefore the test is trying to download them from pypi. Sadly this package doesn't have a maintainer and I don't want to put in the effort to package these all just to fix this one test.

Fixing test dependencies is indeed the preferred solution, however, as you're not the maintainer I can understand you don't want to add those expressions. Here users of the package (including reverse dependencies) may want to take a role NixOS/ofborg#387.

@FRidh that's a good suggestion, but in this case this package is a dependency of none.

Perfect, then let's not spend any time on it. Whoever chooses to use this package can take that responsibility.
