I have not tried it yet, but I once got burned by compiling LAPACK and
BLAS for dynamic linking.

My mistake: inconsistent use of '-fpic' flag.  Resulting problem:
mysteriously failing routines, changed behavior when running under
debugger.  Solution: Compile _all_ functions in both libraries,
BLAS and LAPACK with '-fpic'.

So, I would suggest that you add the flag to the CCFLAGS, change
CLINKFLAGS, and adjust CLINKER in the ATLAS Makefile if necessary.
HTH.

See ATLAS/doc/LAPACK.txt, then follow hint above.

The compilation of Octave is irrelevant here.  Dynamic libraries are
- err - dynamically linked to an executable.  If they are installed
  correctly, they _will_ be used.
