As far as I read the source code, keeping correct combination
of the versions is rails' responsibility, not redmine's.

The patch 'debian-changes-2.3.5-1' included in the rails
source package overwrites the original gem's version check as follows:

-gem 'rack', '~> 1.0.1'
-require 'rack'
+begin
+  require 'rack'
+rescue LoadError
+  gem 'rack', '~> 1.0.1'
+  require 'rack'
+end
