Gettext on OS X Leopard

Hello there.

I tried to run my Rails app on Leopard.
I usually run it on Linux, but I wanted to test it on my Mac (MBP
2.5GHz, Leopard 10.5.2, Ruby 1.8.6, Rails 1.2.6).

I installed ruby-gettext, and I also installed the GNU gettext through
Macports.
Then I checkout out the code from SVN and copied the locale directory
from my linux machine.
However, when I hit the link that should change my application’s
language, nothing happens.
I did not notice any errors from Mongrel.

Am I missing something?

You can try the linux-hosted app here (look top-right, on the
menubar): http://www.diafragma.gr
