macOS 11 Big Sur and MacPorts

@Ryan - When I start Xcode after updating it tells me it is installing 
needed components, and command line tools *is* one of the components 
updated.  It tells me that explicitly during the install.  Again, the 
"xcode-select install" is not something I've done manually either of the 
last two times I've updated MacPorts.  For me, that step was not 
required when I did the MacPorts update after the Catalina install, or 
just now after the Big Sur install.  MacPorts continues to function as 
expected retrieving and building packages as needed.  I don't mean to 
argue, I am just relaying what I've personally experienced.  Perhaps the 
action is remembered somewhere in Xcode?
