I don't like these hacks at all, and I've noticed that we're seeing similar issues creating user bug reports with bundled rdoc in 1.9.3.

I have plans to make rubygems easier to support 'vendor packages', with the original aim to making it easier for OS packagers to deal with their own bundles more easily. I think Ruby needs the same support.

I do not find the following transcript appropriate:

% sudo /usr/bin/gem list mongrel

*** LOCAL GEMS ***

mongrel (1.1.5)

% sudo /usr/bin/gem uninstall mongrel
Password:

mongrel (1.1.5)
    Author: Zed A. Shaw

    Installed at: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8

    A small fast HTTP library and server that runs Rails, Camping, Nitro
    and Iowa apps.


These are not "good approaches" to the problem, they're hacks and they need to be fixed.
