Rails - Sep 2009 - autotest: No such file or directory - -u (Errno::ENOENT)

Hi there,

I currently can not get autottest to run:

loading autotest/rails
/opt/local/bin/ruby -I.:lib:test -rubygems -e "%w[test/unit
test/functional/home_controller_test.rb
test/unit/helpers/home_helper_test.rb].each { |f| require f }" |
unit_diff -u
