* I didn't find Asciidoc, so you won't be able to (re)build the manpage.
* That's not a problem, if you're building from a release-tarball, because

* install Asciidoc or disable manpage generation with:

the scandir calling convention changed about macOS 10.8. In the past, software used to test for the scandir ABI and use the one that the system used, but probably that has not been done lately, or removed if it was done before.

See [74405bfa3c405e2c316d669fba0a0a744cc6dad5/macports-ports] for a fix from another port that worked there.

I have wondered about a way to add this fix transparently in legacysupport, but so far haven't sorted it out.

[jmroot (Joshua Root)]

It's not an ABI difference, it's just different declared const-ness which the stricter compiler type checking in C++ doesn't like to mismatch.
