What multiarch setup?  We have none.

Or do you call a 64-bit chroot multiarch?

I will make this pledge here: If we are willing to get a 64-bit port
going now, I am personally willing to solve any such build-dep cycle
that arises.

I can make that pledge knowing that this is neither a hard nor an
intractable problem.  Having just solved several of those on netbsd-i386
last week.

Can we get this repository on ftp.debian.org as a real port?

Anyway, doesn't the chroot on alioth already have this?

And that is fairly trivial attainable for a pure-64bit port as well.

Speak for yourself; the speed is a pressing factor for me.  Otherwise,
why would i have just not bought a Xeon?

Can you summarize, or post a link to an existing summary, of exactly
what is wrong there?
