Unfortunately, it doesn’t help to specify a keyword, but one gets a new error:
Error while trying to load definition for system
asdf-test-harness-example from pathname
/Users/evenson/work/asdf-test-harness/eg/asdf-test-harness-example.asd:
The following symbols need to be imported to #<Package "ASDF/INTERFACE">
before they can be exported
from that package:
(:HARNESS-TEST):
I think with some futzing around with EVAL-WHEN around EXPORT statements we can
get this to work.
I’m coming to the end of my day with a Common Lisp Foundation board meeting, so
I will probably get back to this tomorrow.
best,
Mark
