Comment (by cluesch):

 I had the same issue after running the XCode upgrade, the log-file in
 question would be
 {{{/opt/local/var/macports/sources/rsync.macports.org/macports/release/tarballs/base/config.log}}}
 which contains the following helpful message:
 {{{
 You have not agreed to the Xcode license agreements, please run
 'xcodebuild -license' (for user-level acceptance) or 'sudo xcodebuild
 -license' (for system-wide acceptance) from within a Terminal window to
 review and agree to the Xcode license agreements.
 }}}

 So you have to run {{{sudo xcodebuild -license}}} again after the upgrade,
 as you have on initial install of XCode. The problematic part is actually
 that {{{selfupdate}}} fails silently, because without the license accepted
 it does:
 {{{
 localhost% sudo port selfupdate
 --->  Updating MacPorts base sources using rsync
 MacPorts base version 2.5.4 installed,
 MacPorts base version 2.6.0 downloaded.
 --->  Updating the ports tree
 --->  MacPorts base is outdated, installing new version 2.6.0
 Installing new MacPorts release in /opt/local as root:admin; permissions
 0755

 localhost%
 }}}

 Notice that there is no error, but it actually doesn't do anything either,
 the error will just be in the log file. If you accept the license, it will
 go through:
 {{{
 localhost% sudo port selfupdate
 '--->  Updating MacPorts base sources using rsync
 MacPorts base version 2.5.4 installed,
 MacPorts base version 2.6.0 downloaded.
 --->  Updating the ports tree
 --->  MacPorts base is outdated, installing new version 2.6.0
 Installing new MacPorts release in /opt/local as root:admin; permissions
 0755

 Not all sources could be fully synced using the old version of MacPorts.
 Please run selfupdate again now that MacPorts base has been updated.
 localhost%
 }}}


 However now you will have a new warning whenever you compile something, I
 guess this is a follow-on issue from the new SDK or SDK selection in the
 configuration:
 {{{
 localhost% sudo port upgrade outdated
 Warning: Unable to determine location of the macOS 10.14 SDK.  Using the
 default macOS SDK.
 Warning: Unable to determine location of the macOS 10.14 SDK.  Using the
 default macOS SDK.
 Warning: Unable to determine location of the macOS 10.14 SDK.  Using the
