gcc8 does not install in macos 10.14.3

[jhi]

I did first

port selfupdate
port upgrade outdated

--->  Updating MacPorts base sources using rsync
MacPorts base version 2.5.4 installed,
MacPorts base version 2.5.4 downloaded.

and then thought to install the latest gcc which looked like 8.3.0:

port search gcc8
gcc8 @8.3.0 (lang)
    The GNU compiler collection.

but the installation failed as follows:

$ port install gcc8

 cctools

In the future, please use WikiFormatting, fill in the Port field with the port that actually fails to build and add the port maintainer(s) to Cc (port info --maintainers isl), if any.

This is a known issue with an easy solution.
