[ERROR]: You are providing the path to ${_present}
through your environment but no reference to ${_missing}.
To fix this error please specify ${_missing} too.

As an example, if you are using automake-1.12 and have
available aclocal-1.12 you will want to do the following:

    AUTOMAKE="/usr/local/bin/automake-1.12" \\
    ACLOCAL="/usr/local/bin/aclocal-1.12"   \\
    ./bootstrap

Your current environment has:
    AUTOMAKE="$AUTOMAKE"
    ACLOCAL="$ACLOCAL"

        exit 1

else
    AUTOMAKE="$(which automake)"

# Make sure that we have a version of automake that doesn't force
# 'subdir-objects'.

AUTOMAKE_VERSION="$($AUTOMAKE --version | head -1 | cut -d' ' -f4)"
case ${AUTOMAKE_VERSION} in
  1.14)
    cat >&2 <<__EOF__

Mesos requires automake < 1.14 due to incompatibility issues
with the 'subdir-objects' option.

See https://issues.apache.org/jira/browse/MESOS-577 and
please downgrade your automake installation.
