I got farther this time. No errors about missing or wrong versions of OpenSSH. But I am still getting stuck at this:
Password:
t/1_run.t .... skipped: Unable to establish SSH connection to localhost!
t/quoting.t .. Use of uninitialized value $ENV{"LANG"} in pattern match (m//) at t/quoting.t line 17.
I'm not sure what/where this env value is located or how to fix it.
