emerging x11-libs/libxshmfence with the ABI_X86="64 32" in make.conf yields: x11-libs/libxshmfence-1.1 USE="-static-libs" ABI_X86="32 (64) (-x32)" It fails in the ./configure section with: checking for linux/futex.h... yes checking for XPROTO... no configure: error: Package requirements (xproto) were not met: No package 'xproto' found -------------------------- re-emerging xproto doesn't work. This does work: ABI_X86="64" emerge -av1 x11-libs/libxshmfence Perhaps disabling the 32 bit API on 64 bit archs which seems a rather common thing to do. Alternatively you could follow the output of ./configure: Alternatively, you may set the environment variables XPROTO_CFLAGS and XPROTO_LIBS to avoid the need to call pkg-config.
