Hi Christian,
you output looks like a problem I had:
On my 64bit architecture I had to modify the make file for atlas and
append an -fPIC at the compiler flags (I tired that at the
architecture flags, the g77 and the c flags. That did the job).
Otherwise it seems not possible to use the libraries with scipy.
Good luck,
Hanno
