The ports tree still thinks llvm37 is really needed by some of these, 
and trying to pkg delete llvm37 wants to also delete many installed 
applications.  This seems wrong, but I have seen zero information about 
this before, so maybe it is not just my system.  I'd be willing to 
update docs about this, provided someone can clarify just what 
information needs to be there.  `pkg delete -f llvm37' to just delete 
that, then an entry in make.conf to force llvm39?
