This is indeed an unusual situation; most packages on PyPI have a source
archive that can be built with 'python setup.py install'. The python
portgroup has no support for installing from wheels. As you found, the
first complication there is that there is no longer just one distfile…

If you have to install a wheel, pip is the tool for doing that. Whether
you have to in this case is another question.

I haven't tried it, but I wouldn't think their build system would
produce *only* a wheel. The files that go into the wheel would probably
be there in some build directory too. It looks like building from source
has its own complications though. You need Bazel, which needs JDK 8. You
also need the CUDA SDK for Nvidia GPU support.
