You don't have this  problem with g77 3.2.3 building Octave as the blas
embedded in cholmod was also built with g77 3.2.3. However you then have
an issue of linking the C++ 4.3.0 compiled code with the g77 3.2.3
compiled code.. You have to compile everything (even the external
libraries) with a consistent set of compilers

Why do you need to compile Octave at all? As you've noticed it is a
complex process due to the large number of dependencies. Why not use a
Fedora or debian based system and use the Octave 2.9 versions that are
pre-built (correctly) for these systems..
