Please change directory into one of the gem installation directories:

cd c:/Ruby/lib/ruby/gems/1.9.1

And try yo create a file there:

ruby -rfileutils -e "FileUtils.touch 'foobar'"

Repeat the same process with the second directory shown by gem env (C:/
Users/Matt/.gem/ruby/1.9.1)

If you or Ruby cannot write to these directories, it will fail.

If you installed Ruby with administrative privileges and you're not a
member of Administrator group, then you're hitting a permission issue.

I would recommend setting GEM_HOME and GEM_PATH environment variables
to a different place (one that you have control) and try installation
again.

Also, please remove gemcutter from your gem sources:

gem sources -r http://gemcutter.org

As Gemcutter is now gems.rubyforge.org
