ASM is a little above my level...

I guess its a problem with obfuscation. Why not have the build script download and deob Computercraft as it does with TC and TE?

Yes, it was an obfuscation problem, but not the one you'd think. The .asm file needs to be obfuscated by CCObf.
ComputerCraft doesn't need to be deobfuscated, because it's searge mapped, and we don't reference any minecraft methods when we compile against it.
