Okapi @1.39.0: hdiutil: attach failed - no mountable file systems

[ryandesign (Ryan Carsten Schmidt)]

​Okapi cannot be installed on older systems because the disk image on which it is distributed is formatted using APFS:

Checksumming Protective Master Boot Record (MBR : 0)…

hdiutil: detach failed - No such file or directory

Please mark the port with known_fail yes on systems that do not support APFS so that the buildbot can skip them. A more friendly user-facing message might be good too.

If this port is supposed to work on earlier systems, please work with the developers to get them to distribute it on an HFS+-formatted disk image in the future.

Thank you for solving this mystery. We had a user report being unable to mount the DMG on an older system, but I never managed to figure out why.
