[matplotlib-devel] Problem compiling matplotlib from master

[Nelle V. <nel...@gm...>]

Hello,

Since I've updated my master branch, I have a new error when installing
matplotlib. It seems it doesn't find a header file from numpy:

I've reinstalled numpy (development version), and I tried to reinstall
everything (on python 2.6) but I still get the error. Am I the only one
having installation problems ?

Here is the (partial) traceback:
