This commit
    http://tug.org/svn/texlive/trunk/Master/bin/amd64-freebsd/asy?view=log
says
    asy for amd64-freebsd from Nelson, amd64-freebsd13-gcc.tar.xz

So at least the two seem consistent.

I didn't have much time earlier, so Karl took the existing binaries.

I tried to build my own version on FreeBSD with clang++ and using
static libraries for as much as possible, but there's one last
building block missing, namely proper support for OpenGL via freeglut.
If I manage to build those binaries, they should be "more standalone".
(I could submit my latest build right now, but it won't support
OpenGL.)

The current list of dependencies includes:

librt.so.1 => /usr/lib/librt.so.1 (0x800784000)
libz.so.6 => /lib/libz.so.6 (0x80078c000)
libncurses.so.8 => /lib/libncurses.so.8 (0x8007a6000)
libc++.so.1 => /usr/lib/libc++.so.1 (0x8007fd000)
libcxxrt.so.1 => /lib/libcxxrt.so.1 (0x8008cd000)
libm.so.5 => /lib/libm.so.5 (0x8008ef000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x800921000)
libthr.so.3 => /lib/libthr.so.3 (0x80093b000)
libc.so.7 => /lib/libc.so.7 (0x800968000)

Asymptote version 2.64 [(C) 2004 Andy Hammerlindl, John C. Bowman, Tom Prince]

WebGL 3D HTML rendering
