Hi, just yesterday i got bitten by this issue. FYI:

# verlib "pep386" (from https://bitbucket.org/tarek/distutilsversion)
>>> from verlib import NormalizedVersion as V
>>> V("0.2a1") <  V("0.2.dev0") < V("0.2")
True

Also there is a bug in that version of verlib because it contradicts
pep386 here:

>>> V("0.2rc1") < V("0.2")
False


# setuptools ¿?
>>> from pkg_resources import parse_version as V
>>> V("0.2.dev0") < V("0.2a1") < V("0.2")
True

# distutils
>>> distutils.version.LooseVersion("0.2.dev0") < distutils.version.LooseVersion("0.2")
False
# O_O

cheers,
SAn
