Did you /really/ use a -i?  RubyGems 0.7.0 doesn't allow that option
anymore.  It should have been ...

    # gem install log4r-1.0.5.gem

If you did use a -i, then we might have conflicting versions of gem loaded

Try this with the --traceback option.  This will give us a stack dump.  E.g.

  gem list --traceback

Thanks.
