Good afternoon all...

“All” I write hoping that I am not alone on Usenet...

Somebody wants to use one of my Gems and upon uninstalling an older
version encounters an error that I cannot interpret. Here is the latest
report from this user in form of actually executed calls to gem and the
results on screen. If you have an idea, let us PSE waste some
Internet-ressources on the discussion of this topic... ;) TIA

Did you ever solve this by any chance? Without fail whenever I have to use ruby/gem to install things, it's a PITA. I can't uninstall anything because of this issue..
