Indeed I am configuring Octave with "--disable-64".

Do you see "octave_idx_type num;" in MPI_Send.cc ?
I have only this definition for "num" on line 79 of MPI_Send.cc:
int num = s.length ();

BTW, is your build of Octave done with "--enable-64" ?
Does this still require building all dependencies with 64 integers as explained
here:
http://wiki.octave.org/Enable_large_arrays:_Build_octave_such_that_it_can_use_arrays_larger_than_2Gb.
?
What version of BLAS/LAPACK are you linking to? What other libraries do you
need to compile with custom options?
