I have a new amd64 system. I had the system up and running with x86, but then decided to switch to 64bit. I reformatted my hd and used 2006.0 stage3 amd64 tarball. Once I had the system installed I am attempting to do an emerge -uDav world. The first few packages compiled fine but the compile bombed out at gcc. I have tried to recompile several times (along with a couple of emerge syncs). I have tried using distcc with another amd64 system and using only the host cpu. Each time the failure has been at the same place.

I don't know where the compile is picking up 32bit anything. This should be a pure 64bit environment.
I figured this out on my own. It seems that gcc fails if you do not have ia32 emulation enabled in your kernel. Why I need ia32 emulation in a 64bit environment is beyond me. After enabling those two options I was able to emerge gcc 3.4.5.
