TypeError installing launchpadlib using setup.py

[Diogo Matsubara]

I tried to install launchpadlib following the instructions in https://help.launchpad.net/API/launchpadlib and got a:

TypeError: use_setuptools() got an unexpected keyword argument 'min_version'

[Māris Fogels (mars)]

This results from launchpadlib's ez_setup.py script and simplejson's setup.py interacting badly.

simplejson has a hacked ez_setup.py script that adds a 'min_version' argument to ez_setup.use_setuptools(), and simplejson's setup.py file calls this. This works fine when simplejson is the *first* package to load the ez_setup module. However, we use ez_setup in launchpadlib. launchpadlib installs first, calling its own vanilla ez_setup.py. The simplejson setup.py runs second, pulls launchpadlib's ez_setup module from the path, calls it with the 'min_version' argument, and BOOM.

The min_version hack is unnecessary as of ez_setup.py revision 60812. The 'version' argument to ez_setup.use_setuptools() now has the same functionality.

This is fixed in the version of launchpadlib pushed to Launchpad. Once we move Launchpad over to using that version, it'll be fixed there too.

This is now fixed in the version of launchpadlib you can download from Launchpad, so I'm marking it fix released.
