If you are taking from svn, then you need the autoconf etc tools, but if
you are using tarballs then the configure script will be already built
so it won't be needed in that case.

no, ogg2 is not required, and AFAIK the vorbis codec may not be working
with it just yet.

I don't think you can state that in general, as the second encoding will
operate on different pcm input. Given the same encoder settings it's
unlikely to loose much.
