I'm sorry I don't have an answer for you, but, to provide another  
data point, I managed your commands without Octave complaining.

octave-3.0.5:12> xx = 0:.1:10;
octave-3.0.5:13> yy = xx .^ 3;
octave-3.0.5:14> plot (xx, yy)
octave-3.0.5:15> print -dps foo4.ps
octave-3.0.5:16>

I'm using Octave 3.0.5 and gnuplot 4.2 patchlevel 5 on Mac OS X 10.4.11.
