Comment(by singingwolfboy@…):

 Actually, it might be more correct to separate the mercurial port into two
 parts: the Python module installed in the site-packages directory, which
 would follow the module naming convention of py2{5,6,7}-mercurial; and the
 CLI client (/opt/local/bin/hg) and all the support files under
 /opt/local/share/mercurial, which would simply be called mercurial. I.E.
 separate the parts of mercurial that are dependent on Python version from
 the parts of mercurial that aren't. We might also need to use the
 port_select behavior in Macports to switch between what Python version you
 want for the mercurial CLI client.

 This seems like the most robust solution, but also the most work. :(
