Moxie tests fail on 5.28.0-RC1

[DannyThomas]

Works fine with 5.26.2
macOS 10.13.3
NB because the BerkeleyDB libs & headers no longer come with macOS,
I've installed MacPort's db48 and linked them under /usr/local/BerkeleyDB

Tests were run but no plan was declared and done_testing() was not seen.

Looks like your test exited with 255 just after 1.
