Actualy, since aspell FTBFS and libaspell15c2 was never in the archive
for all archs there shouldn't be any package linked against it. The
transition rules said to wait before uploading rdepends. This
obviously needs to be checked.

Also, all sources should duild-depend on the new aspell or some buildd
will use the libaspell15c2 instead and still get the 'broken' depeneds
entry and delay removing libaspell15c2.

So I would say just drop libaspell15c and reupload anything that was
already wrongfully uploaded again.

Why? This is exactly what a versioned conflict is for. The packages
have to be upgraded as pair and apt/dpkg will hapily do that. Having
libaspell15c2 conflict libaspell15 makes it no easier than having
libaspell15 conflict the old aspell-bin.

Going back to libaspell unbreaks a bunch of rdepends and means aspell
can go into sarge on it's own, without waiting for the rats tail to
get transitioned as well. I think that is well worth it.

My 2 cents,
