No. The "port select" mechanism is for a user's convenience only. A port may not rely on the user having selected anything in particular, or anything at all. A port should build itself using exactly the programs it wants (i.e. ${prefix}/bin/python2.7) and not rely on e.g. "python" being anything in particular or even existing.
