Re: [Matplotlib-users] mac osx 10.6 matplotlib installation error: "lipo: can't open input file: /v

**update** matplotlib 1.0.0 setup worked on one but did not work on a second Mac OS X 10.6.6. The second one again failed with a missing dependency. It seems to depend on what previous packages may have been installed.

The following seems to be a complete fix:

1. On Mac OS X 10.6.x (in my case...6)
2. Install Apple Xcode (requires registration as an Apple developer)
3. Install MacPorts http://www.macports.org/
4. Check that all library dependencies for matplotlib in Python 2.6 have been satisfied by first running (with Administrator privileges):
	sudo port install py26-matplotlib
(this will use MacPorts script to install matplotlib 1.0.0)

5. (optional) you can reinstall now matplotlib from http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-1.0/matplotlib-1.0.0.tar.gz/download

**now** it works :-)

PS note to matplotlib developers. The above may suggest that matplotlib may have a dependency that is not present on a virgin OSX Xcode machine but which is incidentally installed by some other package usually present on a developer's machine and so whose absence is not noticed when preparing the installation script.
