And further, it should probably issue some kind of warning to let
people know that setuptools is ignoring this option in any scenario
when it is ignored... I didn't even notice until I started looking in
my site-packages folder to uninstall stuff.
In this particular case I don't need --root or --record because I
already am tracking all of that with bdist_mpkg in a different way.
The reason I want single-version-externally-managed behavior in the
first place is because I don't want to have to try and deal with
having the packages try and edit easy_install.pth. I suppose I could
have it install in an egg-dir and drop in a separate pth, but ideally
I wouldn't have to do anything. All I want is the old behavior plus
the egg_info metadata.
There are three features bdist_mpkg has that make it currently useful
 No bootstrap issue, Mac OS X ships with a GUI installer that
understands .mpkg/.pkg bundles.
 No permission issue. Mac OS X will prompt for authorization (like
"sudo") when and only when it is needed
 Installing Other Stuff. bdist_mpkg is used to install examples,
documentation, headers, dependent libraries, etc.
The third feature is important in a few cases, because packages like
pygame have dependent libraries (the SDL frameworks), PyObjC has
Xcode templates, etc. Most packages are perfectly well suited to eggs
as currently specified, though. I'm not too concerned with the other
two features, because those are rarely an issue and can be easily
resolved with a GUI front-end to easy_install that combines ez_setup-
like functionality for bootstrapping.
