macOS 11 Big Sur and MacPorts

My perception is that the "xcode-select --install" is not needed, as the 
message below indicates.  For me, every time Xcode is updated, the first 
time I start it following its update I am prompted to update components, 
and the current version command line tools are installed.  Perhaps the 
manual xcode-select is required if you don't actually start Xcode the 
application following its update.

My experience with MacPorts and Big Sur (as before with Catalina) was to 
simply follow the MacPorts update instructions, after updating and 
starting Xcode as described above, but without that manual xcode-select
