I can replicate it reliable by cleaning (renaming, actually)
~/.cache/common-lisp and loading libssh2. Is there another way
to ensure that COMPUTE-ACTION-STAMP is called with :JUST-DONE NIL? (I
don't understand how exactly this affects JUST-DONE, but it does.)

I anticipated this would be a problem. So, NATIVE-NAMESTRING is not acceptable.

I hoped that ASDF would smooth out working with pathnames for
CFFI-GROVEL as much as possible; providing UIOP seems to be this much.

Thank you for this example.
If DEFAULTS is a pathname of an existing file, ENSURE-PATHNAME seems
unnecessary. Under this assumption, the following definition appears
(defun exe-filename (defaults)
(uiop:parse-unix-namestring (pathname-name defaults)
(N.B. Neither definition prepends "./" to relative paths.)
