I'm hoping that the build that's currently preventing me from typing rapidly will also allow me to run the main test suite manually and see what's broken.

Pflug. The two flavors of test suite (command-line and interactive) are broken in *different* ways as a result of recent changes to the testing engine.  

In the interest of getting this fixed quickly, I'm going to describe these, just in case anyone has suggestions.

1) The command-line tests fail like this:

   given: #(struct:error-result "require: namespace mismatch; reference (phase 0) to a module \"/Users/clements/plt/collects/test-engine/racket-tests.rkt\" that is not available (phase level 0) in: test")

When I attach the test-engine/racket-tests module to the user's namespace, these failures turn into:

   given: #(struct:error-result "link: module mismatch, probably from old bytecode whose dependencies have changed: variable not provided (directly or indirectly) from module: \"/Users/clements/plt/collects/test-engine/racket-tests.rkt\" accessed from module: 'stepper-module-name-762 at source phase level: 0 in: test")

This module does appear to provide a macro called 'test', so ... I'm not sure how to interpret this message. It doesn't look like something I can solve by re-running raco setup.

(FWIW, for those of you with deja vu, yes: this is the same question I cc:'ed to plt-dev before.)

2) The interactive tests fail like this:

   given: #(struct:error-result "namespace-variable-value: test~object is not defined")

I haven't worked on this one yet... but it looks like this is also something that was added this month.
