To force a port to build with a compiler that it is not presently defaulting to, you do this, for example:

sudo port -v install lldb configure.compiler=macports-clang-6


There are values for configure.compiler in here:

<https://trac.macports.org/wiki/UsingTheRightCompiler>

You must realize that this is heading into "Advanced MacPorting" territory, you can break things, things may not work, etc, etc.

But that is what explorers yearn for ....
