Maybe have a look at the Vagrantfile (and at the developer docs), maybe 
you can get some hint there about what is missing / what went wrong:

OK.

Looks like some header file is missing. Maybe that?:

See the Vagrantfile, search for pyinstaller or borg.exe.

Yes, a working python program is a requirement, so it first needs to 
compile the C / Cython stuff and have all the libraries / headers 
installed also.
