$ sudo STATIC_DEPS=true /Library/Frameworks/Python.framework/Versions/ 2.6/bin/easy_install lxml Password: sudo: STATIC_DEPS=true: command not found
On linux 'true' is a command: $ whatis true true (1) - do nothing, successfully Apparently that is not available on Mac OS X. Can you try with STATIC_DEPS=1 ?

I would advise against using sudo easy_install. This will cause trouble by mixing the system python and the softwares it expects vs. custom ones. If it were me, I would even raises an exception in easy_install if run under root without any prefix option. That's an ever-ending source of trouble. Most of the OP problems have nothing to do with easy_install or even python, but with sudo. sudo does not propagate env variables (more exactly, it has strict rules about which variables to reuse). Do not use sudo, and your problem will disappear. On python 2.6, a good way to avoid sudo is to use --local to install things in $HOME/.local (I don't know how to do that from easy_install --local is an install option to distutils). Otherwise, install things in a directory which is in your PYTHONPATH. I for example use $HOME/local on mac os x, and install everything there for python < 2.6. David

That's not the issue. The point of STATIC_DEPS=true is to set an environment variable in the environment that easy_install is running in. So the problem here is not knowing how to invoke sudo (something like "ENV=val sudo -E cmd" would do the job on top of my head, not sure though - just "sudo -i" and then you have a normal root shell though). But that doesn't seem to be the point of this email here. If you want to help out with that you should probably find the thread on python-list and participate there. Regards Floris

Apparently that is not available on Mac OS X.
The problem is that sudo expects a command. "STATIC_DEPS=true" is not a command. An "export STATIC_DEPS=true ought to be ok. Building lxml is historically quite a pain on osx. It keeps improving though. The most sure-fire way of getting it to run is to use buildout in combination with the staticlxml recipe at http://pypi.python.org/pypi/z3c.recipe.staticlxml I haven't seen a problem report about that in the last 6 months :-) I agree with the sentiment of the original email that the initial impression is, shall we say, sub-obtimal. For me, this is one of the strong points of buildout: once you buy into the general idea, it solves a whopping load of problems for you. Isolation, installation, setup. And recipes like the staticlxml one to solve those pesky weird corner cases! reinout -- Reinout van Rees - reinout@vanrees.org - http://reinout.vanrees.org Software developer at http://www.thehealthagency.com "Military engineers build missiles.
