I contacted Lukas Renggli asking for advice regarding the current
problem with update 7109 and possible solutions.  He OK'ed my forwarding
the response to the list.

Note in particular his theory (with which I agree) that this likely
occurred as a result of having published .85 twice to two separate
repositories.  This suggests that the simplest way to solve this might
be to find the other copy of .85 and then I can replace the current copy
in the 310 repository with it.

I think we added this feature to www.squeaksource.com sometime last  
year. There were too many people complaining about it too often we  
had to manually delete the file and remove the version trough an  
inspector from the model. In the process we also merged some changes  
of Impara, for example to move and copy packages between  
repositories. Philippe added some other new features, like tags. He  
also improved the search speed. You can get the latest version on  
www.squeaksource.com.
