Do I need 32bit libxml2 for python on a snow leopard?

I have a hell of a scrapy installation time on my sl mbp. it requires libxml2, so I decided to install this. installing it from macports does not seem to reset the python binding.

installing it from the source using scrapy instructions ( here ) sets the python bindings, but when I run python -c, import libxml2 "I get an architecture mismatch:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "libxml2.py", line 1, in <module>
    import libxml2mod
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-    packages/libxml2mod.so, 2): no suitable image found.  Did find:
    /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-    packages/libxml2mod.so: mach-o, but wrong architecture

when I explicitly create the libxml2 dll as 32-bit, this error goes away, but then libxslt will not build due to the fact that some other library will not be 32-bit. I'm afraid to keep pulling this line. so the question is only python 32bit? am i doing something stupid here?

edit is python 2.6

edit 2 - by popular request, I am consolidating @Ned Deily amazing answer here. all to him on credit, I just publish the steps that I took based on his answer:

if you trick mac ports (and didn't install anything else through them that you need), nuke them.

$ sudo rm -r /opt/local

add the following to /opt/local/etc/macports/variants.confto prevent the entire unix library from loading with the following commands

+bash_completion +quartz +ssl +no_x11 +no_neon +no_tkinter +universal +libyaml -scientific

install macports python version

$ sudo port install python26

set prerequisites for <

sudo port install py26-libxml2 py26-twisted py26-openssl py26-simplejson py26-setuptools python_select
sudo python_select python26

check that the correct python is selected: run it $ which python, which should say something in the lines '/ opt / local / bin / python', and that at its discretion there should be a link to / opt / local / bin / python 2.6.
