what setting to use to force only arm64 (Apple Silicon) binaries/libraries, no universal ports?

[Kenneth Wolcott]

Hi;

what setting to use to force only arm64 (Apple Silicon)
binaries/libraries, no universal ports?

I already use 'port -s install' and 'port -s upgrade', etc...

I understand that this won't work for dart and java (and others that
are similar) as they are SDK...

I also understand that a port that I might want might not exist for
arm64 (eg: dlang).

Thanks,
Ken Wolcott
