Subject: Howto bind BGP to single interface?

Trying to determine what is wrong with "strict bind yes;" under "protocol bgp". 
 The docs suggest that my syntax is correct.

protocol bgp vultr {
        local as 1234;
        source address 111.22.33.44;
        # strict bind yes;      # Fails if uncommented
        import filter accept_all;
        export filter export_bgp;
        # import none;
        graceful restart on;
        multihop 2;
        neighbor 11.22.33.44 as 11111;
        password "xxxxxxxxxxxxxxxx";
        }
