Redmine

I have the same problem as reported here, but I am running 2.3.3. I just did our monthly machine updates & rails was updated to 3. I have had to install the fastercsv gem, along with installing bundler, but no matter what I do, the installation can't find the fastercsv gem.

My Gemfile also looks like the one in the above link:

source 'https://rubygems.org'

local_gemfile = File.join(File.dirname(__FILE__), "Gemfile.local")
if File.exists?(local_gemfile)
  puts "Loading Gemfile.local ..." if $DEBUG # `ruby -d` or `bundle -v`
  instance_eval File.read(local_gemfile)
end

# Load plugins' Gemfiles
Dir.glob File.expand_path("../plugins/*/Gemfile", __FILE__) do |file|
  puts "Loading #{file} ..." if $DEBUG # `ruby -d` or `bundle -v`
  instance_eval File.read(file)
end

We need to stay on 2.3.x because several of our plugins aren't playing nicely with 2.4.x, & we use this system and those plugins extensively (I have looked into alternatives, but haven't found anything that could replicate). Here's my environment:

Environment:
  Redmine version                2.3.3.stable
  Ruby version                   1.8.7-p352 (2011-06-30) [x86_64-linux]
  Rails version                  3.2.16
  Environment                    production
  Database adapter               MySQL
Redmine plugins:
  redmine_extended_watchers      0.0.2
  redmine_inline_note_images_plugin 0.0.1
  redmine_issue_checklist        2.0.5
  redmine_ldap_sync              1.3.0.stable
  redmine_mailwrapper            0.1.2
  redmine_pdf_documents          0.0.1
  redmine_silencer               0.2.0
  redmine_startpage              0.1.0
  redmine_wiki_extensions        0.6.3

So, is redmine 2.3.x simply incompatible with rails 3? Am I totally screwed?
