Hi all,

I just wrote a small recipe for buildout that installs an egg from its develop version and tarballs it. So far, so good, I got it to work fine with a few example packages.

Now I got a problem when trying to use the "executable" option in the buildout.cfg file: it seems to have no effect. The recipe runs with the default python from the system (2.5) not the one I supply in the executable option (2.4)

I attach my buildout.cfg and the recipe.

Am I doing something wrong ?

Thanks, Martin
