Prodding Ubuntu to upgrade to OPAM 1.2 would be extremely helpful.  Jon, Dave, would you have any contacts there that might be interested?   The Launchpad bug pickup seems to be a little hit and miss...

Also, I know it never seems like the right time to do this, but testing that OPAM 1.3dev does *not* have this problem is extremely important.  It would be nice if the trunk branch of OPAM had a deliberate syntax mismatch and was doing this redirection/rewrite dance as a matter of course.
