The other thing: post-texmf does a 'texconfig rehash' that is equivalent to mktexlsr, so after installing tex, it will find the fonts.
So I suppose that this dependency is not needed. However, before I upload, I will check that it works along with lilypond.

You'll only have to check what happens (postinstall scripts) if you install ec-fonts-mftraced first, and
install tetex later.
