I need some help installing lxml under MacOS 10.8 with Python 2.7.2. I have this version in a directory: lxml-lxml-70a122c I'm using the instructions here: http://lxml.de/build.html#building-lxml-on-macos-x Here's what I typed: sudo python setup.py build --static-deps --without-cython It grinds for a while and fails with this message: clang: error: no such file or directory: 'src/lxml/lxml.etree.c' I've tried a number of other approaches and gotten nowhere. Using macports, it wants to replace my Python 2.7.2 with something like 2.7.5_1, and if I do, I can't even start Python. Can anyone recommend how to proceed at this point?
