diff -u between the current patch file and the updated patch file
The current port restricts the legal erlang versions to 16 thru 20. I have added version 21 to the list and tested it on RELEASE 11.2 p10, RELEASE 12.0 p5, and current r348271, for amd64. I have also run the unit tests by doing a make, changing into the work directory work/cuttlefish-2.0.11, and executing "rebar eunit skip_deps=true". All tests seem to pass on all three versions of FreeBSD.
