Hmm..

  That failed.

created a new chroot 'ch46'

created a new repo in ch46 and copied the needed gcc46 files and libtool, then
tried to use 'pacman -U':

pacman -U gcc-4.6.3-1-x86_64.pkg.tar.xz gcc-fortran-4.6.3-1-x86_64.pkg.tar.xz
gcc-go-4.6.3-1-x86_64.pkg.tar.xz gcc-libs-4.6.3-1-x86_64.pkg.tar.xz
gcc-objc-4.6.3-1-x86_64.pkg.tar.xz libtool-2.4.2-4-x86_64.pkg.tar.xz

  Huh? So how do you set up a chroot with gcc46?
