I think this stack overflow question [1] sort of sums up the problem --
setuptools develop is kind of a hack and only really works if the source
structure matches the installed structure. That used to be true of
matplotlib, but installing different packages based on the Python
version breaks that assumption.
A suggestion in the Stack Overflow entry is to install symlinks to fix
this, and indeed doing this works:
cd lib
ln -s dateutil_py2 dateutil
We can probably automate this in the setupegg.py script, but I don't
think I'll have a chance to get to this today. We can't just include
the symlink in git, since it should point to the version that
corresponds to the user's Python.

This is related to using develop mode. I never use that (I use
virtualenvs instead), so this doesn't get much testing. This seems to
have broken when we started to ship separate versions of dateutil for
python2 and python3. setuptools doesn't seem to like the fact that we
rename dateutil_py2 to dateutil when installing (since in develop mode
it doesn't really install or move anything). That's problematic, of
course. I'll have to see if there's another way to handle this.

Hello,
With a fresh
git clone git://github.com/matplotlib/matplotlib.git

sudo python setupegg.py develop
Starting ipython --pylab I get this error:

124 from dateutil.relativedelta import relativedelta
ImportError: No module named dateutil.rrule
Installing dateutil 1.5 fixes this.
mpl install log shows the following:
OPTIONAL DATE/TIMEZONE DEPENDENCIES
dateutil: matplotlib will provide
pytz: matplotlib will provide
Will dateutil be shipped with mpl or this line needs to be updated?
Thanks.
