Hi, I'm a matplotlib developer and I will posit a guess about what is going on. matplotlib optionally installs pytz and datetuil if it is not found on the system at install time. You can override the default behavior by copying the file setup.cfg.template to setup.cfg and editing it to turn off the pytz and dateutil installs::
## Date/timezone support: pytz = False dateutil = False It looks like perhaps you are getting the ubuntu datetutil and the matplotlib datetuil, but this is just a guess. The ubuntu packager will probably want to rely on the upstream pytz and datetutil, and turn off matplotlib's install by modifying setup.cfg as described above.
