That's what I did, but then trying to do gem install watir, I got the error.
See below: now I am getting a different error:
C:\devkit>dk.rb install
[INFO] RubyGems override already in place for c:/Ruby, skipping.
[WARN] DevKit helper library already exists for c:/Ruby, skipping.
C:\devkit>gem install watir
ERROR: While executing gem ... (Zlib::BufError)

C:\devkit>gem install watir
