I am running a 3 day old nightly build of the IDE on Debian 7.1 (cannot run Debian 8.x on this computer due to problems with video driver), on HP s5713 AMD Athlon-II X2 240, 3GB DDR2sync800MHz with 500 GB HD.
What specifically am I missing in the Debian OS that is needed to support this IDE and this Arduino board?
