Redmine

I'm having problems getting CVS working, below are the details.

$ sudo -E RAILS_ENV=production script/about
Environment:
  Redmine version                          2.0.2.stable.9774
  Ruby version                             1.8.7 (x86_64-linux)
  Rails version                            3.2.5
  Environment                              production
  Database adapter                         MySQL
Redmine plugins:  no plugin installed

Under Administration > Settings > Repositories, I see:
[x] Cvs     (Red !) /usr/bin/cvs     1.11.23

And of course, in a project, I cannot add a CVS repository. When I choose CVS as a SCM, it gives the error message:

Scm command is not available. Please check settings on the administration panel.

Of course, the fact that Redmine is showing the version of the cvs command, and it doesn't work, is strange.

Any help/ideas are greatly appreciated.

Thanks,
Mark Mercado
