I am attempting run, in 1.8.6, an fxruby sample called babelfish.rb

babelfish.rb requires a gem called tranexp

I installed the gem and  
gem list --local produces (in part)  
produces  
tranexp (1.0.1)

I, of course, tried to run babelfish.rb.

Of course, it wouldn’t run …

* * *

babelfish.rb:4:in `require’: no such file to load – tranexp (LoadError)  
from babelfish.rb:4

* * *

What would prevent tranexp to load when all other gems load just fine?

do you have a require ‘rubygems’ in there?  
-r
