I think there was a mistake in the last version of z3c.form demo. (trunk)
After running ./bin/buildout, it fails due to a develop = . z3c.form
in buildout.cfg. I think z3c.form was supposed to be pulled from svn
with a svn:externals set to z3c.form in the z3c.formdemo directory.
Checking out z3c.form inside z3c.formdemo seems to solve the problem.
