(these are just a lot of suggestions... take it with a grain of salt)
Right... so for some reason jQuery isn't included properly (I know that from
"Error: $ is not defined")... although I'm not sure how you are even able to
get that far given the other error you said you had.
It's interesting that javascript_include_tag (line 7) is throwing the exception
"word is not defined"
Looks like that problem is in the ExecJS Gem -- is that default in Rails 3.1?
Did you add that? Remove that Gem from your Gemfile, rebuild the gems (bundle
install) and see if the problem goes away.
I guess that Gem is part of Rail's default package now? (That is, automatically
included in the Gemfile when you make a new app)
Not actually sure what your problem is but it looks like that Gem is aliasing
the javascript_include_tag which is making it not too happy.
Maybe try examining the line of code in execjs that it is hiccuping on (You
should be able to find that from your stacktrace)? Perhaps that will have clues
as to why it is hiccuping when trying to execute javascript_include_tag
