config.ru file

    require 'myapp2'     run sinatra::application

myapp2.rb

    require 'rubygems'     require 'sinatra'      '/'     'hello world'     end

you're missing top of stack trace, looks problem require.

in config.ru change

require 'myapp2'

to

require './myapp2'

or

require file.expand_path("../myapp2", __file__)

ruby 1.9.2 no longer has current directory in load path, require 'myapp2' isn't able find app file in same directory.

if working on local machine, not on heroku, you're using different version of ruby, 1.8.7. idea install 1.9.2 locally you're using same version in development , production. alternatively change heroku stack you're using; have @ the heroku stack docs
