Well, from what you posted, require 'rubygems' is done somewhere in the 
code you load (that's the custom_require line right there) and I guess 
the captcha gem tries to load GD and cannot find it.
So your problem is either that GD is not correctly installed or that you 
don't have the correct GD version.
Try to isolate the problem by making a small unit test of just a test 
program that does only the one thing you're trying to do here:

require 'rubygems'
require 'captcha'

var= CAPTCHA::Web.new
p var.to_html("captcha_temp")

so that you don't have all the Rails snick-snack to wade through.

Also, here's a link to a discussion talking about the captcha  gem 
http://groups.google.com/group/uso-dev/browse_thread/thread/63642201fb194e0d

I think it mentions that it needs the ruby-gd gem and that that gem is 
source-only (so you need to compile yourself)
