I'll think about how to change this. It's a tableview, so just
loads from its datasource (which is the actual state of the
symlink). There might be another way around it, but it's not
just a reordering of code, unfortunately.

Thanks for making that test, since that's exactly what I expected
to happen. I'm currently arguing with myself over whether
to allow changing the architecture, or just hiding it from
the user (i.e., removing that table column). If no one knows
that it exists, we might all be happier!

The architecture-changing is a transient thing, as I see it; in
another 10-15 years, I assume MacTeX will finally drop support
for PPC and 32-bit Intel, right? :-)

thanks for the comments!
