I don't think the planteccrma "extras" url in the apt configuration is
the problem. That is an old snapshot. Most probably the newer fftw was
installed (maybe automatically?) through yum, which is most probably
pointing to the full extras repository. 

What happens if you _now_ try to install fftw3 and octave through apt?

To see where things are coming from you can query packages with
apt-cache, for example:
  apt-cache policy fftw3
  apt-cache policy fftw
should print all versions available and from where, there will be a "*"
next to the one that's actually installed.
