Why are we using pbr to get the version of an installed package, instead of asking pkg_resources?
Just wanted to +1 the above. I've also considered pbr a packaging/install tool. Furthermore, I believe having it as a runtime requirement makes packagers life more complicated because that means pbr will obviously need to be added as a runtime requirement for that package. Flavio
