Update Oct 15, 2012
PyPi is now showing matplotlib at 1.1.0 so this issue is resolved. Install matplotlib via:
pip install matplotlib
Outdated Information Below
PyPi shows matplotlib 1.0.0. However, when I install matplotlib via pip into a virtualenv, version 0.91.1 is installed.
- Why the difference in versions?
- Is there a way to pip install matplotlib 1.0.0?
Research
It appears that matplotlib’s DOAP record on PyPi is pointing to the correct version. Below is the DOAP record for reference:

Even though matplotlib 1.0.1 has been release, this issue still persists.
I’ve experienced the same problem. I have no idea why it happens, but I do have a fix; use the -f option in pip to tell it where to find the matplotlib sources. (This works in requirements.txt as well).
