[xml] install libxml2-python into home directory

[Brian Austin <baustin berkeley edu>]

Hi,
I'm trying to install the libxml2 python module into my home directory 
because I don't have permission to write in any of the system directories. 
I've been able to build the module, but I can't figure out how to alter 
the install directory.

> python setup.py install
...some very normal looking output...
running install_lib
copying build/lib.aix-5.2-2.4/libxml2.py -> /usr/common/usg/python/2.4/lib/python2.4/site-packages
error: /usr/common/usg/python/2.4/lib/python2.4/site-packages/libxml2.py: 
Permission denied

Is there something in setup.py that is analogous to configure's --prefix?

After this is installed, will I need to set anything like a python 
equivalent to LD_LIBRARY_PATH?

Thanks for your help and patience.
