Причем

# emerge --info | grep -i distcc              
distcc 3.1 x86_64-pc-linux-gnu [disabled]
DCCC_PATH="/usr/lib64/distcc/bin"
DISTCC_LOG=""
DISTCC_VERBOSE=""

В ebuild вот такая штука

src_compile() {
    strip-flags

    echo > "${T}"/test.c || die 
    $(tc-getCC) ${CFLAGS} -c "${T}"/test.c -o "${T}"/test.o || die 
    case $(file "${T}"/test.o) in

    *) die "Failed to detect whether your arch is 64bits or 32bits, disable distcc if you're using it, please";;
    esac

Проблема с nss появилась после

pump emerge -uNDa world

Версий nss пробовал несколько.

Куда копать?
