No, those are not the solutions here. If there is an issue with the 
build on 10.13 we should fix that instead, rather than apply 
after-the-fact bandaids.

The first thing to determine is if its a MacPorts specific issue due to 
how the build is performed, or an upstream issue. Either way please 
submit a bug report to macports trac so the discussion on this can 
continue there.
