Thanks both.  Pushed out a pre-release with Jeremy's patch:

	gem install --pre unicorn 5.5.0.1.g6836

commit 6836d0674efdb1a6b79953285f10d8edd7e20432

Will tag and release 5.5.1 final in a day or two assuming all
goes well.

Subject: [PATCH] unicorn_rails: fix regression with Rails >= 3.x in app build

Note: `unicorn_rails' was only intended for Rails <= 2.x projects
in the old days.

Fixes: 5985dd50a9bd7238 ("Support default_middleware configuration option")
