Attiny 84 with Wire.h doesn't work (?!) or how does the SFR02 will?

Hi,
I am using the attached code which is the mix of the

  1. Example SRF (Sonic Range Finder) http://arduino.cc/en/Tutorial/SFRRangerReader
  2. Example of the 7 Segment IC Shift register 74HC595 found at instructables : http://www.instructables.com/id/Temperature-Displayed-on-4-Digit-7-segment-common/

I have verified it with the UNO and everything worked perfect.

Now I wanted to go to the Attiny 84 and verified beforehand the BLINKING and FADING examples to work perfectly (so Bootloader worked), but then I got errors regarding the SFR section where the Wire.h was not recognized.

Any idea how I could use the Attiny with the Devantech SFR02?
btw: the IDE I am using is 1.0.4.

Many thanks in advance

There is a wire library for ATtiny84:
