Build issues on Raspberry Pi's Debian

[cnlohr]

I get the following error after installing prerequisites:

make: *** [debian/rules:36: clean] Error 255
dpkg-buildpackage: error: fakeroot debian/rules clean subprocess returned exit status 2

Solution: include dh-python to the prerequisites. And add dh-python to the debian/conrol file's build-depends.

Then, I get the following error:

dh_auto_clean: error: failed to run pyversions

I tried installing it via pip3, but to no avail.

Any ideas?

I was able to "get around it" by just symlinking py3versions to pyversions. That feels incredibly ugly, though. It looks like the build tool ignores the override in debian/rules.
