Unfortunately this means that I had to uninstall octave3.2-headers, which I need to build Octave packages. After this, reinstalling my custom-built atlas libraries kept generating the same errors: dpkg -i /usr/src/atlas/libatlas3gf-base_3.8.3-18+custom4_amd64.deb (Reading database ... 422051 files and directories currently installed.)

Unfortunately it is faster (+15%) for matrix inversion, but slower for Schur decomposition (-16%), part of LAPACK, with respect to the precompiled libatlas3gf-base_3.6.0-24_amd64. I always read that custom compilation of Atlas takes forever, but it only took 13 minutes on AMD Athlon(tm) II X4 630 Processor 2.8 GHz.
