Redmine

In the case you are doing a totally fresh install of redmine with a totally new Ruby installation (specially done for running Redmine), the file "Gemfile" does not exist.
So, you get that exception.
I think this tutorial has been done by someone who already has a fully functional ruby environment.
But there are case where peoples, like me, are asked to do a redmine installation from scratch, on a machine that doesn't already have a ruby installation.
In that case, if you follow the wiki page, you fail.
Because you got a fresh install of ruby without Gemfile.
So i think the wiki page should add a little precision : In the case you are on a fresh ruby install without an existing Gemfile, you have to do a "bundle init".
Without that, someone trying to install ruby+redmine fail.
This is trivial for a ruby adict, but this wiki page is potentially readen by peoples not familiar with ruby.

The stack is roughly like this
- ruby
- rails
- rails-application

The Gemfile is usually part of the rails application.

That is not correct, the Gemfile is always part of the redmine download package. If it would not be, then which versions of which gems would bundler use?

Gemfiles are application-specific and technically don't belong to ruby itself.

You don't, because it is in redmine-2.3.3.tar.gz you just downloaded.

I'm closing this as it isn't a defect per se, let's discuss this on the forums...
Oh, Mischa already did while I was writing this...
