Try wiring it to the Arduino headers. Make sure the board is /not/ attached to the basebord when programming.
Can you try writing the programmer to the Arduino headers instead of the ISP connection?

checked the programmer with another ATMega328P based board and it is working OK.I can confirm this, my USBtinyISP won't work with the Sensors board (and I tried from both Linux PC and Mac) and does work (from both Linux PC and Mac) on other Arduino's.
I get the following from both Linux and Mac:
avrdude: initialization failed, rc=-1 Double check connections and try again, or use -F to override this check.
Error while burning bootloader.
I used short jumpers to connect the USBtinyISP and the 6 pin ISP connector. As noted below you can't actually plug the USBtinyISP onto the ISP pins it's too tight a fit. Board powers up as expected but no joy on flashing the bootloader.
Tomorrow I'll clean my desk off, dig through my Arduino stuff and find a real Arduino and rig to flash it from that.

I've not tried the ISP connector. It may be that we screwed it up somehow. George, have you tried it? This was the very first batch of boards, so there are things that I know are wrong and will be fixed before going into production.

That will solve the connector problem and also make it compatible with more shields. I'm pretty confused at this point, to the point of suspecting multiple > faults.

Since you can't get USBtinyISP to program the board, do you have an arduino board handy that you can run the ArduinoISP sketch on? I used the following instructions for flashing the bootloader: https://www.arduino.cc/en/Tutorial/ArduinoISPWill do. I haven't got a proper arduino to hand but I can fudge it with an old breakout board...
