Well, if the source code is published, and can be compiled, then from a technical perspective it can be turned into a port. As to the patent license requirement, we have some precedent for that. For example, the +bytecode variant of the freetype port. This enables the patented TrueType bytecode interpreter. When installing with this variant, the port advises the user of the situation and directs them to http://www.freetype.org/patents.html for more information. An opencore-amr port could do similarly, assuming that is acceptable to the developers.
