The ebuild currently has LICENSE="as-is" which most likely is wrong. - No license is included in the package's tarball. - HOMEPAGE appears to be dead. Can you please ask upstream for clarification under with terms this package can be distributed?
Mail to upstream sent, but it bounced: ... while talking to www.vdrportal.de.: >>> DATA <<< 554 5.7.1 <Wicky@www.vdrportal.de>: Relay access denied 554 5.0.0 Service unavailable <<< 554 5.5.1 Error: no valid recipients
I don't know, if Wicky is still active in the VDR community, didn't heard alot of time anything from him.... so, added RESTRICT="mirror bindist" LICENSE="all-rights-reserved" to the ebuild, this should it fixed for now...
