I believe two changes have created this problem:

 - The feature ID for the IMP Language Meta-Tooling changed a few
   releases ago, from org.eclipse.imp to org.eclipse.imp.metatooling.

 - The bundle ID for the LPG IDE changed a few releases ago, from
   org.eclipse.imp.lpg.runtime to org.eclipse.imp.lpg.ide.

Now, both versions of the IMP Language Meta-Tooling feature are present
on the update site, so given the ID change, the Update Manager may try
to install both versions, with bad results.

I think we should remove the old feature version from the update site
to avoid further confusion.

As a work-around, simply don't select the older version (0.1.88) in
the Update Manager when installing IMP.
