A download error during do_compile(). My guess is that we have a
missing dependency. With python, Ruby and some other packages we have
to be careful as their builds will actually cause downloads to happen
if a dependency is missing (python will fetch eggs, ruby will fetch
gems...). When I have time I usually do builds with IP tables rules in
place to force errors when these fetches happen so that I can catch
them and fix them. Downloads should only be done by the fetcher and
not bundler, pdb etc. If you see an error about downloading and you
are not in do_fetch() something is wrong.

Start by adding python-vcversioner as a DEPENDS in python-jsonschema
and you should be good to go.
