*cough* I think you're a little too confident here... I tried pax

$ gzip -dc subversion-1.0.1.tar.gz | tar xvf -
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Archive contains obsolescent base-64 headers
tar: Error exit delayed from previous errors

file doesn't even think it is a tar file:
$ file subversion-1.0.1.tar
subversion-1.0.1.tar: data

I'll try it on a different machine later. I tried this on amd64 and
it's possible pax doesn't work righ ton this platform for whatever
reason (i.e. a bug).

Given that we've now tried 3 different tar implementations looking for
one that produces portable and correct tar archives and so far we
haven't found one... I'm not quite as confident of this as you are.

Well I don't think any decision has been made. Justin and I both have
that as a goal. If it can be attained remains to be seen.
