I installed the following gems:
crowd-stefanwille (0.5.11)
crowd_rails (0.5.11)
soap4r (1.5.8)

in order to connect to crowd. I installed the modxcms-redmine_crowd-1e48029 Redmine plugin but started getting the dreaded "Object is not missing constant Project!" error. I have narrowed it down and can make it go away by removing require 'crowd' from the plugin init.rb. Crowd.rb is contained in the crowd-stefanwille gem. I am not sure what to look at to fix this error.

Thanks for your time.
