Yes. This prevents MacPorts from rebuilding them as +universal if
a dependent's architecture doesn't match.

Those ports are wrong.

I expect that most ports install at least one library. In our case,
false positives are better than false negatives.

The default is "yes".

By doing something like this:

	sudo port install pstree configure.compiler=macports-clang-3.6

No. MacPorts automatically sets CC, CXX, etc. in the configure
environment based on the value of configure.compiler. It does not add
these variables to the build environment.

Why not? Plenty of other ports do so. The more documentation, the
better.
