My guess would be that mod_ruby is running with $SAFE > 0, but rubygems 
and/or twitterland doesn't work in those conditions.

Try showing SAFE=<%= $SAFE %> to see if that theory is right.

Also try running your standalone ruby script with ruby -T1 (or add 
$SAFE=1 to the top) to see if it barfs in the same way.

Aside: I'm afraid you'll find not many people use mod_ruby these days. 
As far as I can see, most people write Rack-based web apps. To run them 
with Apache you'd either proxy to a standalone ruby webserver 
(mongrel/thin/unicorn/rainbows!), or inside Apache using Phusion 
Passenger, a.k.a. mod_rails.

That's not to say that you can't make it work, it's just that you might 
not find many other people using mod_ruby to help you if you have 
problems.

Equally, if a particular app or library doesn't work with $SAFE=1, 
perhaps it should be modified so that it does.

Regards,

Brian.
