 > I believe that's correct. I suppose it could be changed to use MacPorts
 git/svn if available, for a hypothetical situation in which the copy found
 or specified at MacPorts configure time is not sufficient.

 Probably not so hypothetical for users of older OS versions that install
 prebuilt binaries. And supposing they do build from source: doesn't the
 MacPorts configure script attempt NOT to find dependencies under $prefix?
