Hello,
While I'm not the Maintainer; it appears to me that the port is
choosing the $BASE version library, before attempting to use the
ports version. As seen here:

LIBEVENT_STATIC_BUILD_DEPENDS=3D ${LOCALBASE}/lib/libevent.a:devel/libevent2

Note that devel/libevent2 is chosen *after* ${LOCALBASE}

Have you attempted to reverse that order, and try again?
