Can the sancp-1.6.1-r2 ebuild have the ~amd64 keyword added? It currently has only ~x86, however I was able to successfully compile and run it on my machine (Intel Xeon P4 w/ EM64T) using the amd64 x86_64 build. Per a forum suggestion (http://forums.gentoo.org/viewtopic-t-556519.html), I enabled ~x86 for sancp-1.6.1-2 via package.keywords and it emerged fine, albeit with several warnings regarding variable types. It does run and seems to be functioning well enough for additional testing via ~amd64.
