[TxMt] Module problems

Having a hard time to get ruby scripts to recognize modules. Checked "$:" and got the following:

/usr/lib/ruby/site_ruby/1.8 /usr/lib/ruby/site_ruby/1.8/powerpc-darwin8.0 /usr/lib/ruby/site_ruby/1.8/universal-darwin8.0 /usr/lib/ruby/site_ruby /usr/lib/ruby/1.8 /usr/lib/ruby/1.8/powerpc-darwin8.0 /usr/lib/ruby/1.8/universal-darwin8.0

The module I am trying to "require" is in this list (the first listing in fact). When I try to to run script from TextMate "command + R" the script keeps failing. When I ask text mate to get required "shift + command + D" TextMate complains that it can not find require "snmp". When I run script from the terminal though it finds the 'require' I requested. Any ideas?
