Download and extract : http://www.antlr3.org/download/antlr-3.1.3.tar.gz
go to /runtime/python
and run python setup.py install

When I try to do that, it defaults to putting things in /Library. We can't write to /Library, nor to /, due to recent MacOS changes. Is there a way to tell setup.py to target a different location?
