Unable to read group information from repositories

[Jerry James]

I just tried to do an install of x86-64 Rawhide into a virtual
machine, using boot.iso dated 17 Mar 2009.  I got up to the part where
it formats the filesystem.  At that point, I got an error dialog box
that says:

"Unable to read group information from repositories.  This is a
problem with the generation of your install tree."

Now what?
