Sure, thanks for the offer of help! otool output is first:

Segmentation fault
OK, I have to agree with you: My problem is not related to yours. I noticed you were using Python 2.3.5; I am using 2.4.1, so I tried 2.3.5 to see if it made a difference. (Actually, 2.3.5c1, I did not yet upgrade since.) I ran into compilation problems, which were attributable to an old version of Pyrex (0.9) in my Python 2.3 libraries, which I fixed by upgrading Pyrex to 0.9.3 I doubt that is your issues, but you also may want to look at /opt/local/lib/python2.3/site-packages/Pyrex/Compiler/Version.py
After that, I pass all the tests... So I am totally at a loss with your issue.
What I will do is send you my etree.so obtained this way (separately); can you see whether it segfaults on your machine? You will have to set export DYLD_LIBRARY_PATH=/opt/local/lib because it will expect to find the libraries in /usr/local/lib, not in /opt/local/lib Hopefully our libxml version mismatch will not affect you (ok, not too likely but I want to try.) Actually, maybe you could also send me your copy of etree.so?

Paul, I might've missed it in the thread, but we do we know your version of libxml2/libxslt yet? It just might be relevant.
At least thanks to Marc-Antoine we know lxml *can* work on Mac OS X, which is sort of a relief to me. :)

Paul, I might've missed it in the thread, but we do we know your version of libxml2/libxslt yet? It just might be relevant.
According to his otool -L, /opt/local/lib/libxml2.2.dylib (compatibility version 9.0.0, current version 9.16.0) /opt/local/lib/libxslt.1.dylib (compatibility version 3.0.0, current version 3.12.0)
i.e. libxml 2.6.16, libxslt 1.1.12

Ah, okay, I missed that. That should work; I'm using this on my debian box.
Paul, did you ever have it working without segfaults in the past? I seem to recall you did, but perhaps I am mistaken.

Yes, but when I built my own Python, instead of trying to use DarwinPorts. I tried Marc-Antoine's binary and it worked.
