Comment (by PerMildner):

 Replying to [comment:31 ryandesign]:
 > When we refer to "the installer", we usually mean the pkg files that
 install a pre-compiled binary of MacPorts base. That's not the part that
 detects bsdtar's capabilities. MacPorts base itself tests those
 capabilities every time it tries to install a port.

 libarchive installed it will test that bsdtar, and otherwise it will test
 the macOS bsdtar.
 My point was that, presumably, there is no need to test the `bsdtar` that
 "MacPorts libarchive installed" (if any). The test is, if I understand
 correctly, a way to detect old versions of `/usr/bin/bsdtar` (and those
 would never crash during the test, regardless of the state of MacPorts).
 So, from I read above, it seems the right test would test
 `/usr/bin/bsdtar` _only_ which would both test the right executable _and_
 fix the crash dialog.

 But note that I have no idea how the MacPorts base works or is supposed to
 work. I am just going by the information in this thread.
