The ebuild currently has LICENSE="as-is" which most likely is wrong. - The perl script doesn't include a license (only a warranty disclaimer). - I cannot find any license information on the HOMEPAGE. Can you please ask upstream for clarification under with terms this package can be distributed?
Mail to upstream sent.

Fixed.
