Okay I'm mainly asking beforehand so I won't have to shoot myself in the head twenty minutes from now.
I suppose I'll find/figure out one way or the other anyway
Can I just source the 32dev.sh and then run sbopkg -i if the source for the package I want to create isn't 64bit capable?
Oh wait. I might need to change the $ARCH variable to x86_64 too, right?
