Comment 3 for bug 482993

there have been two further workarounds reported in this InkscapeForum topic:
<http://www.inkscapeforum.com/viewtopic.php?f=29&t=3588>

A) change the default python version back to Python 2.5

terminal command:
  defaults write /Library/Preferences/com.apple.versioner.python Version 2.5

B) compiling from source:

Packages downloaded:
- lxml-2.2.4.tar.gz
- numpy-1.3.0.tar.gz

Python version used:
$ which python
/usr/bin/python
$ python --version
Python 2.6.1
$ lipo -info /usr/bin/python
Architectures in the fat file: /usr/bin/python are: x86_64 i386 ppc7400
