FWIW, I'm using zc.buildout to build a project-local (non-system- 
installed) libxml2, libxslt, and lxml.  This works out reasonably  
well on the Mac (caveats below) and on other platforms (known success  
on Centos/RHEL, Ubuntu).  It's a bit of philosophy to not use the  
system-installed libs for this, so you may not like this solution if  
your philosophy differs on this point.

The big caveat on Mac is that you must start python with  
DYLD_LIBRARY_PATH=/Users/gary/Dev/MYPROJECT/parts/libxml2/lib:/Users/ 
gary/Dev/MYPROJECT/parts/libxslt/lib
for the project-installed libraries to be found (otherwise you still  
get the system ones).  You can get around this by having a wrapper  
script that inserts the values in the environment for you; for  
instance, zdaemon will do it for you if so configured.

My zc.buildout setup is similar to what Martijn Faassen blogged about  
last year.  If anyone is interested I'll dig up the details-- 
particularly the differences.
