Dear list, I am having problems installing matplotlib (from source) and fipy. I had installed numpy from source and it is running well: :~$ python -c "import numpy; print numpy.__version__" 1.6.1 After being trying to solve this problem on matplotlib list, I was recommended to ask numpy list. I copy-paste the errors below and forward the mails from matplotlib users.

I do not understand why matplotlib can not see numpy. Please, see the forwarded message. My notebook description: Linux 3.0.0-13-generic #22-Ubuntu SMP Wed Nov 2 13:27:26 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux Thank in advance for your help Regards, Lucia

Just making sure, where/when did you get your mpl source? There was a bug in mpl master for a while that would not parse numpy's development version number correctly, but it has been fixed since then. Ben Root
