Redmine

Hi Everyone,

I have just installed the newest redmine server (3.2.1) on a new Fedora v23.

When trying to start, the following occurs. Does somebody has any idea how to proceed?

The requested gem is in the directory.

Thanx

 [r3m0t3@srv-somnius redmine]$ bundle exec ruby bin/rails server webrick -e production

 => Run `rails server -h` for more startup options
 => Ctrl-C to shutdown server
