Looks right to me:

  octave:1> pkg load communications
  octave:2> I = gf([1,0,0,0;0,1,0,0;0,0,1,0;0,0,0,1])
  I =
  GF(2) array.

  Array elements =

     1   0   0   0
     0   1   0   0
     0   0   1   0
     0   0   0   1

rpm -V octave-communications shows no problems?

After "pkg load communications" do the paths from the rpm show up in
the Octave runtime path?

    [1,2] = /usr/share/octave/packages/communications-1.1.1
