Package: python-numpy Version: 1:1.0.4-6 Followup-For: Bug #464784 After transition to gfortran it appears that the matrix multiplication function (numpy.dot) is now linked to the slow version in numpy/core/multiarray.so instead of being linked to the faster ATLAS version (in previous package version available under numpy/core/_dotblas.so). Another side effect of the transition is that ATLAS libraries are not found by /usr/lib/python2.4/site-packages/numpy/distutils/system_info.py which makes it impossible to compile extension modules linking to ATLAS and LAPACK with f2py. ld seems to be configured correctly, here is my /etc/ld.so.conf:
