ATtiny84 in arduino-1.5.7

Hello everybody, by now i were using arduino-1.0.5 to program an ATtiny85 using this instructions from MIT : http://highlowtech.org/?p=1695 and everything worked OK.

But when i try it in arduino 1.5.7 to insert the ATtiny boards in the board.txt (in hardware file), I can't find the boards in the IDE. Does anybody know something about this problem?

Thanks in advance ;)

There is still an error message while you compile your code

Third-party platform.txt does not define compiler.path. Please report this to the third-party hardware maintainer.

I'll havent yet the time to make further tests but code get ompiled.

Upload later this month.
