Humm, no feedback yet. So I guess I make a version modulation for 2.x,
put everything in fftw, make fftw2 depend on fftw and then make fftw2
an emty stub. On the other hand there are **NO** packages depending
on fftw2, so can I skip including the old version?

Josh: Be invited to release the updated package at will, just let me
know :-)

Phil: Are you ok with this? I don't want to package everything up just
to redo things on submission ;-)
