I need to test this later on, but that sounds strange as we are
successfully compiling asymptote against boehmgc 8.0.4 in MacPorts.
OK, admittedly, that's two minor versions newer from what we ship in
TeX Live; I don't know whether that detail matters. (Why is asy in TeX
Live using 8.0.2 as opposed to the latest version?)

Here are some (slightly hard to find) logs from yesterday:
    https://build.macports.org/waterfall?last_time=1553796775
and the binaries:
    http://packages.macports.org/asymptote/

It built fine out of the box on all OS X versions >= 10.9.

10.8 and older failed due to

but I'll try to fix that next by switching to a newer compiler (in MacPorts).
The compiler used for building TL already meets these criteria (I just
didn't have time to try it out yet).
