I've tried this and run in to problems a bunch of times in the past. Does anyone have a recipe for installing lxml on OS X without MacPorts or Fink that definitely works?
Preferably with complete 1-2-3 steps for downloading and building each of the dependencies.
Thanks to @jessenoller on Twitter I have an answer that fits my needs - you can compile lxml with static dependencies, hence avoiding messing with the libxml2 that ships with OS X. Here's what worked for me:
cd /tmp
curl -O http://lxml.de/files/lxml-3.6.0.tgz
tar -xzvf lxml-3.6.0.tgz
cd lxml-3.6.0
python setup.py build --static-deps --libxml2-version=2.7.3 --libxslt-version=1.1.24
sudo python setup.py install
