It did help. That was exactly it – I had named the file fastercvs.rb. When I renamed it, it worked fine. Thanks for your help, Glenn ----- Original Message ---- From: James G.

The file you required though, fastercsv.rb, does not have a FasterCSV constant anywhere in it. (It’s a shim that loads some other code.) My guess is this: you named your own file fastercsv.rb. When you try to require the gem, Ruby is finding your file first and it fails to load because FasterCSV was never defined. If I’m right, you just need to rename your file and it will work. Hope that helps. James Edward G. II
