Comment (by gagarine):

 I know those are details, but it can help a lot to avoid confusion.
 Especially "port install" is going to be the first command that a new user
 try. Having a warning their is certainly not the best experience.

 To avoid "Warning: xcodebuild exists but failed to execute" we can know if
 dev tool are installed using

 {{{
 xcode-select -p
 }}}

 or

 {{{
 xcode-select -version
 }}}


 Then for the "Warning: Xcode does not appear to be installed; most ports
 will likely fail to build." perhaps somethings like "Xcode does not appear
 to be installed; some ports may fail to build. To hide this message in the
 future type 'port xcode-warning-hide'".
