Rails 2.1.1 worked find in my development environment, but I was  
unable to start the mongrel cluster in production. I received the  
following error:

/usr/lib/ruby/gems/1.8/gems/activesupport-2.1.1/lib/active\_support/  
core\_ext/rexml.rb:8: uninitialized constant REXML::VERSION (NameError)

Has anyone else run into this?

Thanks!

it’s because you’ve got an older version of ruby, where the thing  
giving the version of rexml was REXML::Version and not REXML::VERSION

update that file to what it is on edge  
([http://github.com/rails/rails/tree/master/activesupport/lib/active\_support/core\_ext/rexml.rb](http://github.com/rails/rails/tree/master/activesupport/lib/active_support/core_ext/rexml.rb)  
) to make the pain go away.
