macports python-lxml dependency

[Niels Olson]

okay, so this has nothing to do with PixelSnap per se, but it points
out something awry elsewhere in the cosmos: I use the MacPorts build
of Inkscape, and this was the first extension I really wanted to try.
There are a number of extension dependencies, and one of those
dependencies, inkex.py, requires python's lxml, which I installed
through MacPorts (many moons ago, as a dependency for another package,
so lxml should be there, and working, but I checked anyway, and
macports py25-lxml package is definitely installed). So somehow it
seems that MacPorts Inkscape extensions can't find MacPorts lxml.

Which affects anyone with MacPorts Inkscape who want's to use the
marvelous PixelSnap extension.

Just wanted to get that recorded somewhere here. Will post to macports
trac too.

Hi Niels,

Thanks for posting about this issue. I've added a link to this post in the INSTALL file for people who have similar problems. The updated INSTALL file will appear in the next release.

P.S. I'm not currently aware of the simplest way to fix this, but as Niels describes, it's a MacPorts/Inkscape issue. I believe a similar problem exists for Windows builds of Inkscape.

Technically-minded people could probably figure out how to install lxml in a way that Inkscape is happy with, but I'm unaware of a simple fix.

If anyone finds one, post it here!

I fixed the MacPorts Inkscape/lxml problem by building lxml from svn.
First I had to download cython (http://cython.org) and install

~/cython$ sudo python setup.py install

As I'm using the MacPorts variants; when I built lxml, I specified
these two things

sudo python setup.py install
--with-xslt-config=/opt/local/bin/xslt-config
--with-xml2-config=/opt/local/bin/xml2-config
