It isn't. It is designed to use the first compiler in the fallback list
that is available and not blacklisted. It is implicit in this that
compilers earlier in the list are more preferable than later ones.
But why does it not take the lowest *available* version, and why does it tell
me to install (= activate) clang-3.7 rather than install clang-3.6 (from
scratch)?
Because macports-clang-3.7 occurs first in the fallback list. Print out
${compiler.fallback} if you don't believe me. :)
Installed compiler ports are not considered "more available" than
uninstalled ones.
