[Pythonmac-SIG] Lanchd + virtualenv

[Orestis Markou]

No need for a wrapper script. In recent versions of virtualenv, you  
can do this:

     activate_this = 'path/to/virtualenv/bin/activate_this.py'
     if os.path.exists(activate_this):
         execfile(activate_this, dict(__file__=activate_this))
