Is it possible to use MacPorts without Xcode or Apple ID? MacPorts requires XCode. One seems to be only able to install XCode through the App store which requires an Apple Id to install stuff. Is there any way to circumvent this?
Only install Xcode CLI tool, since most of the ports work without Xcode although there's a warning during use.

Quote from Google Summer of Code 2019 for MacPorts


  Phase out dependency on Xcode (done in the main repo)
  
  MacPorts currently requires a full Xcode installation, even though a lot of ports will install just fine with the Command Line Tools package only. Since we also have a number of ports that need Xcode to build, we cannot completely remove the Xcode dependency. Your task would be to provide a way for maintainers to easily identify ports that depend on Xcode and mark them as such, so MacPorts can warn users without Xcode installed that a port they want to install needs the full Xcode package.
