ARPACK vs (BLAS + LAPACK) - build question

[Sergei Steshenko]

Hello All,

ARPACK README file says:

"
   The makefile is set up to build a self-contained library which includes
   the needed BLAS 1/2/3 and LAPACK routines.  If you already have the
   BLAS and LAPACK libraries installed on your system you might want to
   change the definition of DIRS as indicated in the ARmake.inc file.
".

So, when building ARPACK for Octave how do you guys build it - using
the included into ARPACK BLAS + LAPACK routines or using independently 
built BLAS + LAPACK ?

I build BLAS + LAPACK regardless; disk space is not an issue, i.e. if
the chances athat ARPACK will function more correctly with included into
the tarball BLAS + LAPACK routines are better, so be it.

Thanks,
  Sergei.
