Gem install problem on os x

I just got a mac monday and am trying to install ruby-debug, however,
when I do it fails and gives me an error. Its happened with a few
other gems too. I type “sudo gem install ruby-debug” and I get the
following:
Install required dependency ruby-debug-base? [Yn] y
Select which gem to install for your platform (universal-darwin8.0)

  1. ruby-debug-base 0.9.3 (ruby)
  2. ruby-debug-base 0.9.3 (mswin32)
  3. Skip this gem
  4. Cancel installation

Gem files will remain installed in /usr/local/lib/ruby/gems/1.8/gems/
ruby-debug-base-0.9.3 for inspection.

Any ideas?

Exact same problem here.

Is there a solution without having to install “make”?
