Hello,

there is a dependency problem. The captcha gem wants to load
the GD library

http://www.boutell.com/gd/

(which is not written in Ruby).
You'll have to install that and probably one of the Ruby bindings
to GD. 
From a search on Rubyforge, I gather that the Ruby gem GD is now
called ruby-gd.
As the captcha gem you're trying to install has its last release
on March 28, 2004 and the now-name-changed GD/ruby-gd gem releases only
one file, from  January, 30th, 2007, there might have happened some changes
in the meantime, I'm afraid 

Maybe it's good idea to contact the author of the ruby-gd gem
to ask for help ... or use some other turing test gem, like turing.

Best regards,

Axel
