Since this is the first time I have had trouble with the package manager, I have no idea how to do what you just suggested.

I think (and this is wild speculation, probably wrong) that the problem is that the daily builds were calling the early version
of libmyth "libmyth-0.23.0" even though it was an early version of 0.24. When the RC1 came out, they changed the name to
"libmyth-0.24.0", but did not include packaging instructions to remove the version named "libmyth-0.23.0" because most people
will never have installed it. So if I can find a way to get rid of libmyth-0.23.0, the ppa I am using should work fine.

I think the purge you suggested would work, but I need instructions on how to do it.
