Redmine

It isn't, i18n doesn't require rails at all from what I've seen. Plus rails 2.3.10 isn't supported for the moment (weird bugs in redmine due to active record incompatibilities).. Can you confirm (or paste the error you see with i18n install) before we close ?

I get this output:

script/server -e production

Did you make any change to your active_support gem?
We have gem 'i18n', '>= 0.1.3' in 2.3.5 (not ~>) which should not raise this error.
