I took a look and if you do alt-I on "SMSqueakMap default
installedPackagesDictionary" then you can see that it hasn't been "lost"
actuall - there is an entry in the dictionary for the SUnit package with
version '3.1'.

But it doesn't show in the loader - why? Well, let's debug this:

	(SMSqueakMap default packageWithNameBeginning: 'SUnit') isInstalled

You will eventually see that it checks if there is a release in package
SUnit with manual version '3.1'. But there isn't!

And this is one of the "gotchas" in current SM2 - it only shows existing
releases/packages as installed. The same problem would appear if the
SUnit package was completely removed.

Ok, the short of it - there is no knowledge in the map that there ever
was a 3.1 release. I am not sure why - perhaps Marcus removed it?

PS. Assuming SARInstaller has some similar issue.
