pip install'ed mock should not depend on command-line tools

I’ve installed nose and mock into a chroot with some custom code and libraries.

i got following error when running nose:

It appears that mock brought in pbr dependency and that wants to examine something at runtime.

Perhaps a packaging kludge is needed (sdist in the error).

Or just remove it entirely when installing a fixed version from pypi.

This fixed it for me: pip install --upgrade setuptools

This still seems to be an issue and a pretty annoying one as it takes down the whole test-runner.

Python 2.7.12 mock (2.0.0) setuptools (28.3.0) pbr (1.10.0) pip (8.1.2)

By now, it seems that PBR is slowly dying https://bugs.launchpad.net/pbr

Is it perhaps time to remove dependency on command-line tools as OP suggested?

I simply tried commenting out references to VersionInfo, version and version_info and the tests ran fine.
