I tried running the tests on the latest ASDF, using the ECL that one gets from Mac Ports (on Lion). I got a number of test failures.
test-module-depend failed test-module-excessive-depend failed test-multiple failed test-retry-loading-component-1 went into an infinite loop, catching an error and restarting over and over.
I'll collect more information as I can, but thought I should give the update.
