I wrote up something about this[1].

Alire will download and install external packages (e.g. SDL2) if it
knows how to use the host system's package manager. The "nightly"
builds[2] for macOS know how to install via Homebrew, provided that the
external manifest has been updated[3].

If someone wants to upgrade Alire to use MacPorts, I'm sure that would
be welcomed.

Adding aarch64 compilers to the mix makes things somewhat more
complicated.

Does MacPorts provide aarch64 (aka arm64) binary libraries? the object
code and libraries that are linked to produce an executable must be
consistent, all x86_64 or all aarch64.
