OK, so I'll elaborate:

When trying to run setup.py, you get this error:
[iBook:~/Desktop/PyXML-0.8.2] martina% python setup.py build
Traceback (most recent call last):
   File "setup.py", line 58, in ?
     if sys.platform[:6] == "darwin" and \
NameError: name 'distutils' is not defined
[iBook:~/Desktop/PyXML-0.8.2] martina%

The offending code is:
if sys.platform[:6] == "darwin" and \
    
distutils.sysconfig.get_config_var("LDSHARED").find("-flat_namespace") 
== -1:
     # Mac OS X
     LDFLAGS.append('-flat_namespace')

This fails due to two trivial and obvious errors:
(a) there is no "import distutils", instead in line 11:
	from distutils.sysconfig import get_config_vars
(b) the wrong function is imported (get_config_vars instead of 
get_config_var).

The proposed patch fixes both (a) and (b). After this patch it builds, 
albeit with a bunch of warnings (tested with the original Apple python 
on MacOS X 10.2.4)

ciao
