Doesn't it seem a bit much to make the user do that?  What if they want 
Python2.5 by default, but generate_docs is incompatible with it?

I can see that, but on the other hand, it means that generate_docs will 
fail on more systems than bzr will fail on, even though they have the 
same requirement for python2.4.

Perhaps that's acceptable, since generate_docs isn't as critical as bzr, 
but personally, I'd rather do /usr/bin/env python2.4 on both of them.
