COPYRIGHT in the package's tarball says: The author hereby grants permission to use this software at no cost. This software is provided on an "as is" basis, and the author has no obligation to provide support or enhancements. The author is not liable to any party for any damage arising out of the use of this software. This neither grants the right to redistribute nor to modify the software, therefore it doesn't qualify as a free software license.
I've added the above as licenses/jfontain and updated LICENSE in the ebuild.
