[git-buildpackage] Installation using pip fails

[Peter Keresztes Schmidt]

Hi everyone,

I'm encountering a problem when installing gbp using pip since version 0.9.10 and upwards.

<snip>
$ pip3 install --user gbp

Collecting gbp
  Using cached https://files.pythonhosted.org/packages/ea/82/c98eb2649c4e819aaac6c328524c2a1f3f9fdefabad95b5ebf886a2729c2/gbp-0.9.13.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-install-zbvugzil/gbp/setup.py", line 22, in <module>
        from version_parser import parse_and_fetch_version
    ModuleNotFoundError: No module named 'version_parser'
</snip>

Looking at the tar file it seems version_parser.py is missing although it is present in the git repo.
Did something go wrong during the release process or is the error on my side?

Cheers,
Peter
