buildbot was missing msgpack as a propagated build input, but somehow it was
available at build time so the failure didn't show up until runtime. I also
removed unidiff, which was an optional dependency that was accidentally made
required in 3.1.0 and fixed in 3.2.0.
buildPythonPackage started failing if there was no setup.py, so disable the
build and check phases. Also, fix the package name so the python version isn't
duplicated.
While looking at the sphinx package I noticed it was heavily
undermaintained, which is when we noticed nand0p has been inactive for
roughly 18 months. It is therefore prudent to assume they will not be
maintaining their packages, modules and tests.
- Their last contribution to nixpkgs was in 2019/12
- On 2021/05/08 I wrote them an email to the address listed in the
maintainer-list, which they didn't reply to.
