Hi, For anybody reading this thread, a reminder about how to use the systemwide ATLAS (at least on Ubuntu 12.04 LTS). Just do this before building Sage:
apt-get install libatlas3gf-base liblapack-dev cd /usr/lib/ ln -s libatlas.so.3gf libatlas.so ln -s libcblas.so.3gf libcblas.so ln -s libf77blas.so.3gf libf77blas.so export SAGE_ATLAS_LIB="/usr/lib/" I'm personally done with building ATLAS...
