Hi,

I'm packaging GNU Bazaar.  Unfortunately, it doesn't support the GNU
build system.  'INSTALL' contains the following instructions:

When upgrading using setup.py, it is recommended that you first delete the
bzrlib directory from the install target.

To install bzr as a user, run

  python setup.py install --home ~ 

To install system-wide, run (as root)

  python setup.py install

I know how to replace phases.  But how can I call 'python'?
