Once that is corrected (see below), the error is

Expectation is that this will compile without error.

To fix these errors, the file Config.arm64-darwin in src/runtime needs to have the CFLAGS and the OS_LIBS changed:

CFLAGS += -g -Wall -fdollars-in-identifiers -I/opt/local/include/
OS_LIBS = -lSystem -lc -ldl -L/opt/local/lib/

I'm using ports to install various parts, rather than homebrew.

This is quite similar to https://sourceforge.net/p/sbcl/sbcl/ci/9de74a0d4d
