You have started ovsdb-server with
/usr/local/var/run/openvswitch/db.sock. ovs-vsctl thinks that file is
present in /var/run/openvswitch/db.sock because that is how it has
been compiled with.
It looks to me that you are changing default directories at some
places and then letting default directories to be used at other
places.
