check what is the minimum requests version that bitmask needs
we have 0.12.1 in our repo, debian has 0.12.1-1 in wheezy and 1.2.3-1 in jessie and 2.0.0-1 in sid, quantal has 0.12.1 and newer in others. At the moment the package breaks with 0.12.1 and 0.14, but it's possible that we can make fixes to the client to support those versions (and maybe the work to do that is less than the work to backport).
