biarch gcc not built with 64-bit mode?

["Jeffrey W. Baker" <jwbaker@acm.org>]

I'm a little confused about the current state of package.  The version
skew between amd64 port and unstable seems to be wide enough that it
isn't possible to install the system currently.  Certainly I can't
install lib64c6, because it wants to pull in a libc6 which will require
the removal of every package on the system.  By extension lib64gcc1
cannot be installed.  

Should amd64 experimenters continue to use Arnd's packages from June?
