Comment(by ryandesign@…):

 * r74545: committed your patch; in addition, changed license to "GPL-2+",
 changed dist_subdir to match readline port's, since the distfiles are
 already on the mirrors there (no need to make people download the same
 file a second time, nor to mirror it a second time). Joshua, the port
 seems to build fine for universal and for non-default-build_arch as
 supplied; I'm not sure what the `-arch-only` flag does.
