Hi Robert,

Indeed, it works fine with #2. I have added a directory 
/usr/local/include/atlas
and copied all header files from my ATLAS installation in that directory.

# 2: with the ATLAS C-BLAS (http://www.netlib.org/atlas).
CONFIG = -DCBLAS -I/usr/local/include/atlas
LIB = -L/usr/local/lib/atlas -lcblas -latlas -lm

Thank you very much.
