py-matplotlib build failue due to failed py-pyobjc2 py-pyobjc2-cocoa build

[alimoeeny@…]

I am trying to install matplotlib on a Snow Leopard MacBookPro. I managed to install scipy and numpy and mac ports defaulted to python 2.4 which is fine by me. But for matplot lib I receive this error: The following dependencies failed to build: py-pyobjc2 py-pyobjc2-cocoa

I appreciate any help with that.

The problem is that py-macholib needs to be bumped to version 1.2.1.

Is there any specific reason you want the python-2.4 version of matplotlib, as you're running Snow Leopard I would highly recommend using the python-2.6 version, py26-matplotlib.

Thanks for the swift reply. It is my first time using mac ports and it is really amazing.

Actually I prefer python2.6 I tried to install scipy and just used: sudo port install py-scipy and it defaulted to python 2.4 (I mean it installed python2.4 with instructions to install python-select and make the 2.4 default. After your suggestion to use python 2.5 I retried the whole process with py26-* and so far I got py26-scipy and py26-numpy and py26-matplotlib to work. Sill working on the matplotlib backends (py26-wxpython failed, trying py26-gtk now).

Great job with macports.

Currently wxWidgets fails to build on Snow Leopard (#20952), hence py26-wxpython also fails.

I got it working with backend : MacOSX All fine, thanks again.

py-macholib update to 1.2.1 in r62835
