the basic blink sketch somehow doesn't work with my new Arduino Uno. The LED just stays lit for all the time, using a different pin and changing the delay doesn't help. Blink without delay works just fine and so do the other things I've tried out.
My setup: Gentoo Linux Arduino IDE 22 (64bit) GCC 4.4.5 avrdude 5.10
My guess is that somehow delay doesn't work.
EDIT: Building a new toolchain ATM…
