Finally i was able to build and flash the transition branch (pine/kanikani) on Debian Linux for my Peak.
pine is still affected by bug https://bugzilla.mozilla.org/1264226 . The bug was fixed in master a few day ago, so after a “cp gecko/security/sandbox/linux/SandboxFilter.cpp pine/security/sandbox/linux/SandboxFilter.cpp” ./build.sh was successful. Maybe someone can apply the change also to the pine branch.
On http://www.gerloni.net/gp-peak/ you can find my master builds, When I find the time I’ll upload a pine/kanikani build. But i guess i have to switch to blob free builds…
