This is certainly because of a mismatch the compiler used for numpy and 
blas/lapack. I checked the rpm you are using, and it looks like whereas 
blas and lapack are compiled with gfortran, python-numpy is compiled 
with g77. I do not use opensuse myself, but started a project to provide 
binaries for numpy/scipy for this distribution: most of the packages 
like blas and lapack are broken on this platform (I really wonder if 
there was any testing of those packages by the packagers).

The quickest thing would be to install numpy from sources. If you're 
willing to help, I have some binary for numpy with my own blas/lapack 
here, which need some feedback (and updating, too)
