Ebuild for ds9 in the binary form. DS9 is an astronomical package to visualize FITS images. The ebuild to build ds9 from sources is in bug #65657, but does not seem to work for ~amd64. This one fetches the appropriate binaries for both x86 and amd64.
Created attachment 48755 [details] ds9.3.0.3-bin.ebuild (New package)
New version 4.0 compiles on amd64. There is thus no need of this ebuild for now. See http://bugs.gentoo.org/show_bug.cgi?id=65657 for the sources.
