Where exactly is "it"?

Can you talk to the twi device? Did you try twi.scan? It should 
report every device on the twi bus.

Did you enable the twi subsystem?

\ enable twi
\ TWBR = $03, TWPS[10] = $03  ==> 28 kHz (f_cpu: 11059200)
: +twi ( -- )
     $00 TWCR c!
     $03 TWBR c!
     $03 TWSR c!
;
This code snippet works on atmega32. Check the datasheet whether 
it is the same for your controller.
