That would be the opposite of the way that these works today, and I can't
imagine wanting to go through all thousands of ports and switch this. I would
rather educate port authors as to how to use them the way they work today, and
improve the documentation if needed.
path:-style doesn't search $PATH; it looks for a file at a particular path
specified in the dependency, i.e. path:/usr/bin/grep:grep or
path:${prefix}/bin/grep:grep. If the path is not absolute, "${prefix}/" is
prepended to it.
bin:-style searches bin_path.
lib:-style does something similar for libraries.
