You need Arduino 1.x. Make sure you install the sanguino 1.x patch from here.
You also need the LiquidTWI2 library, as described in Configuration.h.
If after this you still have compile errors, post it here.
If you can compile, but can't upload because verification fails, you have the wrong bootloader on the Sanguino. There are threads on how to fix that in this forum.
