strange inability to require config/boot after upgrading to ruby 1.9.2

Question

I upgraded my ruby to 1.9.2 and now when I try to start up a Rails 2.3.5 app with script/server I get this error:

<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- script/../config/boot (LoadError)
        from <internal:lib/rubygems/custom_require>:29:in `require'
        from script/server:2:in `<main>'

But script/server:2 definitely looks correct, and the file config/boot.rb exists in the right place.

Answer 1

Replacing line 2 of script/server with

require File.expand_path('../../config/boot', __FILE__)

works for me (taken from Rails 3)
