Comment (by PerMildner):

 About "we could first look at bsdtar's list of libraries": Since in my
 scenario, the tested `bsdtar` (`/opt/local/bin/bsdtar`) crashes, adding a
 test for its list of libraries would presumably conclude that the tested
 `bsdtar` is unusable. This seems undesirable, since, in the common case
 where `/usr/bin/bsdtar` is new enough to support HFS compression, this
 sounds like MacPorts would needlessly decide that HFS compression is
 unsupported. If MacPorts instead tested `/usr/bin/bsdtar`, which I assume
 would never crash, it would discover that it _does_ support HFS
 compression (if `/usr/bin/bsdtar` does not support HFS compression
 MacPorts could either fall back to testing other locations, like
 `/opt/local/bin/bsdtar`, or just fall back to a somewhat less optimal
 format on those old platforms

 PS. It is not clear to me whether "HFS+ compression" is relevant on
 modern, i.e. APFS, file systems but #60230 indicates that perhaps it is
 (user had problem with that option on an APFS system, running as non-
 root).
