I just pushed some changes to base/master and dports/master to better support
macOS 11 and Apple Silicon, but there's quite a bit of work ahead of us.
Some common issues to be aware of:
1) libtool required an update for the version bump. This means many projects
might need an autoreconf to build correctly.
2) arm64 builds with implicit-function-declaration warnings promoted to error
because vararg and non-vararg functions have differnet calling conventions,
thus a prototype is required.
#2 is easiest to fix when you see it in actual build failures (add a missing
header include or protype), but it's less obvious and more problematic when it
occurs during project configuration. There are many configure scripts that now
fail certain checks because of a missing include. MacPorts base was one such
example, and you can see how I had to fix that here:

Please reach out if you have any questions or concerns.
Thanks,
