Gentoo user eh? We'll have none of that "compile from source" nonsense  
around here laddy, it's a binary distro don't-cha-know... :P [0]

As far as I can tell (running Lucid x86_64 on  macbook pro 4.1 at the  
moment) all apps that require it are multi-processor aware.

If you want to recompile, just export the CFLAGS variable before you  
recompile the code.

Kind regards,

Matt

servers, I just got fed up with a desktop taking 14 days to build!
