Agreed - and that's exactly an example of a case where some form of requiring trace mode in the portfile would be useful.

As to fixing ... the experience many of use have had with /usr/local can probably serve as an example/metaphor for why it's not always feasible to avoid including the wrong version of a header... (and I guess it should be easier to exclude or demote a directory from outside the prefix than to exclude/demote ${prefix}/include ...)

I wasn't completely PC about the exchange I had on the Qt ML: apparently attempts had been made to correct the particular issue I reported, which turned out to be too tricky.
