Arduino DMX Examples not working?

i'm trying power 4 dmx channels arduino diecimila. keep getting error in code saying:
error: port_to_output not declared in scope
this example code arduino website:

now i've modified code in order function properly. per directions given in topic:

the modified code come in next post!

my dimmer not recognise dmx signal. example in forum-post did work me, did not work multiple channels.

does know i'm missing here? in advance!
