It looks like the command that is failing is zig itself when it runs 
`zig build`. Try running this command manually from the zig build 
directory and see if it gives you a more detailed error message.

For reference, the full (very lengthy command) is:

     zig build --override-lib-dir /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_zig/zig/work/zig-0.7.1/lib -Dlib-files-only --prefix /opt/local -Dconfig_h=/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_zig/zig/work/build/config.h install
