Re: package.el can't install a circular depend and it should be able to.

It was intended to do a topological sort of the graph and activate
packages from the bottom up.  If this isn't working then there is a bug.

A real circular graph isn't supported.  I guess it could be, though to
me it seems like this would have to be some kind of packaging confusion.
