Subject: non-interactive gem install impossible?

As you know, "gem install mongrel -y" presents this:

Select which gem to install for your platform (i686-linux)
  1. mongrel 0.3.12.4 (ruby)
  2. mongrel 0.3.12.4 (mswin32)
  3. mongrel 0.3.12.3 (mswin32)
  4. mongrel 0.3.12.3 (ruby)
...

Is there any way to reliably do this non-interactively?

  echo "1" | gem install mongrel -y

does not work, because the proper choice may be 1 or 2 for (ruby) - it's 
inconsistent between versions and various gems.

Please don't say, "use expect" :)

Thanks,
Steve
