You should use the OpenBSD package:

  pkg_add ruby%2.6

The "Bus Error at 0xdfdfdfdfdfdfdfdf" is a strong indication of a
use-after-free bug, since 0xdf is the pattern that OpenBSD malloc writes
to freed memory.  However, since there is an OpenBSD package for it, it
must build successfully with the options and patches that the OpenBSD
ports system uses.

Thanks,
Jeremy
