[Distutils] Can't generate console script with buildout - even when using zc.recipe.egg

[mustapha]

Hi Jim,

I wrote a little patch to add support for old style scripts.
I don't know if it is a good solution (maybe I missed something)

Can you please review it and help me to get it done if I misunderstood.

Many thanks,
