[lxml-dev] lxml Mac installation idea

[Guntsche Michael]

Ok,

A new patch. We always create an universal binary if we are running on  
Macosx > 10.3. Furthermore the environment variables are removed  
before we compile lxml itself.
Going to bed now will test this on my Tiger PPC machine tomorrow  
afternoon.

Gnite,
Mike
