Having trouble installing matplotlib on Mac OS X Lion

Having trouble installing matplotlib on Mac OS X Lion
Hi all,

I had matplotlib-0.99.1.1 working with Python 2.6 on OS X v10.6(Snow Leopard). Today I upgraded to Lion (v10.7) and matplotlib had disappeared. Lion ships with Apple’s version of Python 2.7. Even when I look back at Python 2.6 in the /System/Library/Frameworks/Python/Version/Python2.6, it seems to be gone. OK, I thought I would install matplotlib-1.0.1 in Python 2.7 using easy_install. It failed when unable to find the headers for numpy (terminal output below). Lion comes with numpy 1.5.1 pre-installed. I tried re-installing numpy but that didn’t help so now I’m stuck.

Any suggestions?

Thanks.

Hello William - did you manage to solve this problem without resorting to
building from source?

Thanks!

Hi,

   Have you tried the EPD python installation, it works for me and includes
SciPY/Numpy/ etc.
