well the basics on mac have not been fixed. try extensions>pattern along path and you still get the python error
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
FIVE bug fixes and this still does not work - it's so fantastic no one thought to actually install it or make it easy to install/write instructions for it.
so back to the workaround and most of these extensions doing nothing I guess.
