Also, does your pakage of 1.0.2 have the latest version of avrdude included? I was trying to build and upload for a mega2560 target, and avrdude complained it didn't have a definition for the "wiring" programmer (in earlier version, the programmer option passed to avrdude was "stk500v2" for the mega2560, I think. The "wiring" thing is new.)
Replacing avrdude2.exe and avrdudre.conf with a recent version fixed this. I haven't tested out the "official" 1.0.2 yet, to see if in fact the later version is bundled in that release.
