+== Reinstalling the command line tools == #reinstall-clt
+
+When the command line tools package is installed, a receipt is generated that can be accessed with `/usr/sbin/pkgutil`.
+When upgrading Xcode, this receipt can be lost even though the command line tools remain installed.
+Without this receipt, MacPort cannot determine which version of the command line tools package is installed.
+
+'''Fix:'''[[BR]]
+
+Reinstalling the command line tools package fixes the problem.
+* Download the command line tools package from the [https://developer.apple.com/download/more/?=command%20line%20tools Apple Developer] site.
+* Or, on Mac OS X 10.9 or greater, Software Update can reinstall the package:
+  * {{{sudo touch /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress}}}
+  * {{{softwareupdate -l}}}
+  * [https://support.apple.com/en-us/HT201541 Run Software Update]
+  * {{{sudo rm /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress}}}
+Please note that Software Update will continue to list the command line tools package as outdated so long as the file `/tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress` exists.[[BR]]
+Be sure to remove it once the package is reinstalled.
