Inkscape should bundle lxml on Mac OS X / Save as Optimized SVG broken on Mac OS X

[cadabra]

I tried to Save as Optimized SVG on Mac OS X, but was presented with the dialog below and left with an empty .svg file:

> Inkscape has received additional data from the script executed. The script did not return an error, but this may indicate the results will not be as expected.
> The fantastic lxml wrapper for libxml2 is required by inkex.py and therefore this extension. Please download and install the latest version from http://cheeseshop.python.org/pypi/lxml/, or install it through your package manager by a command like: sudo apt-get install python-lxml
> [ OK ]

I tried to install lxml using `sudo port install lxml`, which succeeded, but it was never found by Inkscape (macports installs into /opt/local).

Instead, I was able to install lxml into /Library (where Inkscape found it) using `STATIC_DEPS=true sudo easy_install --allow-hosts=lxml.de,*.python.org lxml`.

Configuration

 - Inkscape 0.48.2
 - Mac OS X 10.7.2
 - XQuartz 2.6.3 (xorg-server 1.10.3)

Inkscape does have the necessary Python module bundled on Mac OS X. However, Python-based extensions not working is a known issue on OS X Lion: linking as duplicate to Bug #819209 “Extensions do not work with Mac OS X Lion”.
