I was hesitant to suggest it, but try editing 'ruby/lib/uri/common.rb'
(I guess it would be /usr/local/shoes/ruby/lib/uri/common.rb for you)
to remove the reference to UTF_7:

$ diff -u ruby/lib/uri/common.rb.orig ruby/lib/uri/common.rb
--- ruby/lib/uri/common.rb.orig 2011-05-05 16:15:13.103236933 -0400

And see what you get then.
