 > I don't get an update notification for the command line tools. Let me
 try the dev site.

 Apple introduced a bug in Catalina (or Mojave?) that deletes the command
 line tools receipts. See ProblemHotlist#reinstall-clt. Receipts are how
 software update knows what you had installed so that it can tell you if
 there is an update. Since Apple removed the CLT receipts, it cannot tell
 you if an update is available. Apple should fix this bug. I don't know if
 they have fixed it in Big Sur.

 > It looks like Macports is not entirely happy with the command line tools
 installed via/by Xcode. Macports seems to require CLT that get installed
 into {{{/Library/Developer/CommandLineTools}}} by a separate installer
 that one downloads directly from the Apple Developer site.

 Some ports require Xcode. Others will use the command line tools if
 present or Xcode if the CLT are not present. "Command line tools" means
 what is installed in /Library/Developer/CommandLineTools.
