[Matplotlib-users] Having trouble installing matplotlib on Mac OS X Lion

[Bill C. <wcc...@lb...>]

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 Apple¹s 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 didn¹t help so now I¹m stuck.

Any suggestions?

Thanks.
