Un-install and re-install if the installed and specified versions differ.

If, for a package, the version specified by the _VERSION variable
doesn't match the version installed (as indicated by a -done file),
un-install it, and remove the downloaded version, before doing any
installs, so that the specified version replaces the installed version.
