Comment (by RiotNrrrd):

 The responses in this ticket all seem to come from an attitude of "User
 error", as if the OP has done something wrong.

 I have two Macs running Mojave 10.14.6 that have this same exact problem.
 I doubt I did anything wrong when it comes to Xcode installation, yet I am
 in the same boat.


 {{{
 mac:~ root# port install mercurial

 I have Xcode installed and the command-line tools and ''xcrun --sdk
 macosx10.14 --show-sdk-path'' finds the SDK in both places mentioned by
 "Joshua Root":

 {{{
 mac:~ root# ls -ldhF `locate MacOSX10.14`
 lrwxr-xr-x  1 root  wheel    10B Nov  1 18:49

 lrwxr-xr-x  1 root  wheel    10B Nov  1 18:56
 /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk@ -> MacOSX.sdk

 mac:~ root# xcode-select --install
 xcode-select: error: command line tools are already installed, use
 "Software Update" to install updates

 mac:~ root# xcrun --sdk macosx10.14 --show-sdk-path
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk
 }}}

 So why am I getting the warning?
