The LD_LIBRARY_PATH and OCTAVE_HOME environment variables can probably 
fix this problem for you.  They have to be set before Octave starts, so 
you need a script to do that which then invokes the real Octave.  Take a 
look at the octave-wrapper.in file in

  http://hg.octave.org/mxe-octave

for example.

Did you know that there is already a build of Octave and gnuplot for 
Android distributed through the google play store?
