What happened is that on older systems using octave2 libraries versioned
suffix got stripped while linking against that library:

% for d in *amd64; do echo -n "$d "; ldd $d/usr/share/octave/site/m/psychtoolbox-3/PsychBasic/PsychPortAudio.mex | grep liboctinterp; done                                                                              
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1_amd64     liboctinterp.so.3 => not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd14.04+1_amd64   liboctinterp.so => not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd15.04+1_amd64   liboctinterp.so => not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd15.10+1_amd64   liboctinterp.so.3 => not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd+1_amd64        liboctinterp.so.3 => not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd80+1_amd64      liboctinterp.so => not found
octave-psychtoolbox-3_3.0.12.20160126.dfsg1-1~nd90+1_amd64      liboctinterp.so.3 => not found

so they got linked against plain .so which is a symlink provided only by -dev package.
We will fix it for the next upload, thanks for the report!
Meanwhile indeed just install liboctave-dev as a workaround

what was the error?  I wonder if -utils is really what needed or some
missing library somehow
