Right, I understand.  What I mean about not installing the source is
this: today you download and install the package, and put the source
in /usr/local/src or something.  Now in 3 weeks you want to install a
new version.  Well, you might like to run uninstall with the new
source, but that's not necessarily going to work, since it doesn't
even know how you configured the source package.

So the right thing to do is to go into /usr/local/src/pkg and run
./setup uninstall there.  So you just have to remember to keep the old
source around and go and run uninstall when you want to.

But I thought maybe this something that a layered tool should do.
Cabal-get (the client-side tool for Hackgae) might download the source
into /usr/local, keep track of the source packages it has swallowed,
and do the job of uninstalling.  So we left it unimplemented until we
get a better idea of what cabal-get will look like.
