Hi Erik - yay for near-success :).
case $(echo "$files" | wc -l | sed 's/^ *//') in 4|6) ;; *) false;; esac
I went with that sed.
because "wc -l" prints some spaces in front of the number (at least
on macOS).
I'm surprised this has not been seen already. But fine.
At least it's easy one to fix.
export PYTHON=python3
to verify that it works with python 3.xx.
Fingers crossed.
P.P.S. It still needs
export am_cv_sleep_fractional_seconds=false
to correctly run the tests on macOS. Without that, 75-90 tests fail.
I'll write separately about that, since this bug is already plenty long :).
Thanks,
Karl
