Redmine

I'm struggling with my Fedora 18 install of Redmine 2.3-Stable, everything had been going well up until the point of performing (and yes I'm targeting SQL Server):

rake --trace generate_secret_token

After which point I'm presented with this:

rake aborted!

I'm sporting the following packages/gems

Any ideas would be appreciated!
