Ah, clever!

Turns out not to be necessary.  Now that the cheeseshop is back up, I  
was able to check and find out that bzr is in there.  It doesn't  
exactly help though because the tarball is broken.  There's an open  
bug on this:

Great for testing, thanks.  But um, how /do/ normal users tell  
setup.py to install those extra packages?

Again, thanks Phillip.  Now that the Cheeseshop is back up, you can  
grab the package from here:

http://cheeseshop.python.org/pypi/setuptoolsbzr
