From the homepage of project: Versions previous to 0.10.0 used John Elliott's lib765 and libdsk for the +3 support. 0.10.0 includes this support natively, so these libraries are no longer necessary (or used). Reproducible: Always
Created attachment 183474 [details, diff] Ebuild patch to remove the obsolete dependencies
You're right, Fuse emulator version 0.10.* no longer uses those two libraries. Jeremy, please apply this patch file against fuse-0.10.0.2-r1.ebuild, it's tested it on my system. Change the revision number in needed (the old one should be removed, then).
thx -r2 now exists.
