script/generator mvc foo bar fails

hm.. do this watirmark foofoo to create new project

in foofoo do this chmod +x script/generate.rb to enable it to be exectubla (go to fix this)

and finally

script/generate.rb mvc foo bar fails with
No such file or directory - ../lib/foofoo/workflows.rb

issue seems to be in #append_to_file method

me thinks we need to provide full path here. (fails on linux and mac. did not try win).
