You are using pip version 7.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Development is not necessarily done on the Raspberry Pi directly. It would be useful to at least have the package install on other systems, to have e.g. code completion enabled.

I forced skipping the test by setting the environment variable: export READTHEDOCS=True

But system is still 64-bit so not working.
