Estube buscando un poco y lo que encontré fue lo siguiente:

Add this to /usr/local/etc/pkgtools.conf in your MAKE_ARGS statement. It’s
the WITH_NDB=1 switch that will enable building with cluster support, the

MAKE_ARGS = {
‘databases/mysql*’ => ‘WITH_NDB=1 WITH_ARCHIVE=1 BUILD_OPTIMIZED=1
WITH_OPENSSL=1′,
}
