The binaries should compile out of the box with a suitable compiler
even on 10.5 (10.4 might pose a bigger challenge, I stopped targeting
that one loooooooong ago).

The reason for issues is that:
- We can no longer build against libstdc++ v2 as shipped by the system
(no support for C++11).
- I want to build against (native) libc++ rather than some weird
libstdc++ v3 as shipped by external gcc.
- 10.6 doesn't ship with libc++, and the one that comes with MacPorts
is too new to work on Lion.
- I tried building against 10.7 SDK on 10.6, but that produces
unusable binaries for 10.6.
- It's nice to still support 10.6 as long as we can do that without
too much hassle.

I made another attempt of taking libc++ from Lion and putting it
inside the 10.6 SDK. It could be that this is what I already did in
2018, but maybe MacPorts somehow overwrote it in the meantime which
broke on Lion.

Are you willing to test whether
    http://dl.contextgarden.net/build/texlive/x86_64-darwinlegacy.tar.xz
finally works?

If it does, I'll use the same settings to build from the 2019 branch
and commit the two problematic binaries to SVN.

MP version plays absolutely no role in this.
(I build the binaries with clang 9.0 now.)

All my attempts to build asy with all the required libraries on 10.6
seem to have failed so far. Maybe I should do another attempt with
just the barebones program and no fancy stuff.
