Doh! I knew it must be a FAQ, and it was :). Better googling gave me the
answer: the configuration was picking up the libraries for the
libatlas3gf-sse2 package, which is built with gfortran. Numpy is built
with g77, and I need to force it to link with the libraries given by the
atlas3-sse2 package (providing libaries built with g77). The best way is
simply to remove the gfortran altas libraries.
This email from David got me on the track:
I must have at some point installed the gfortran libraries by mistake. I
was taken by surprise because I didn't expect Ubuntu to have 2 versions
of atlas, ABI incompatible.
Sorry for the noise.
