The debugging USE flag for EINA requires valgrind to be installed but valgrind fails to build on the ARMv6j (Raspberry Pi) so this USE flag will cause failure during the emerge of valgrind.

When ./configure is run on the EINA package there are 5 relevent options here: --disable-magic-debug --enable-debug-threads --disable-safety-checks --enable-valgrind --enable-debug-malloc What I was trying to do was enable the internel messages that are only available when compiled with the debug option. Those are separate and distinct from the valgrind memory debugging.
USE=debug should be USE=valgrind.
splitting USE=debug & USE=valgrind has been done in the latest version already
