Compilation of sys-fs/btrfs-progs fails. I have a system with USE=-acl and a kernel also without acl stuff. Is acl needed for btrfs? If yes, the ebuild should check and/or issue some warning. If not, the ebuild should be fixed. x86_64-pc-linux-gnu-gcc -Wp,-MMD,./.convert.o.d,-MT,convert.o -Wall -fno-strict-aliasing -D_FILE_OFFSET_BITS=64 -D_FORTIFY_SOURCE=2 -march=nocona -O2 -pipe

The only program that needs acl is btrfs-convert. I have fixed this to not build/install this program if not using acl USE flag (and to issue a warning). No version bump.
