Hi, again it's been a while. I installed a current Rakudo on OpenBSD 5.5 (amd64) and happily most of the test failures didn't occur anymore.
On Moar I had a clean spectest. On Parrot I had only one failure. (Please note, that I had to install ICU ("pkg_add icu4c"). Without that package some of the last mentioned failed tests produced failures with Parrot as well.) t/spec/S19-command-line/dash-e.t (Wstat: 512 Tests: 3 Failed: 2) Failed tests: 2-3 Non-zero exit status: 2 AFAIU this is expected since Parrot on OpenBSD does not support command line arguments other than ASCII. (Support for UTF-8 and ISO-8859-1 was added for Linux in 2011: http://irclog.perlgeek.de/parrot/2011-01-09#i_3167081.) I didn't try to build and run Rakudo on JVM.
