Created attachment 367978 [details, diff] adds python_compat slots With the version bump from 0.5.21 to 0.5.23 python2_6, python3_2, python3_3, pypy2_0 got lost.
pbr went through a solid revision some time back. python2_6 is dropped by explicit choice, deps don't support pypy and ought not have been there in the first place. Several tests fail under py3.2. Looking at py3.3
added 3.2, 3.3 was already there, pypy doesn't work and don't care about 2.6 (should be removed soon imo)
