I ran into the same issue and resolved it as follows:

You need to have RMagick installed and configured.

Instructions to install Rmagick on windows are here:
http://rmagick.rubyforge.org/install-faq.html#win

However for the Rmagick install to work gem must be at 0.8.11 level.

In my case gem --version reported 0.8.10

So, I did the following to get gem updated:

gem install rubygems-update
update_rubygems

That took care of gem --version (reports 0.8.11)

Then I did the following:

downloaded RMagick-1.9.2-IM-6.2.4-6-win32.zip from the rubyforge site

unzipped it, then ran the following commands from the directory where
the files where unzipped to

gem -install RMagick-win32-1.9.2-mswin32.gem
postinstall.rb

Then ran a simple standalone program (same as the one you tried) that
used gruff and voila! everything worked.

Adding it to my test Rails application was a breeze after that.

Hope that helps.

Raj
