The output of ldd /usr/lib64/python2.7/site-packages/scipy/linalg/clapack.so
is very suspicious with Atlas it should look like this:
ldd /usr/lib/python2.7/site-packages/scipy/linalg/clapack.so
        linux-gate.so.1 =>  (0xb7890000)
        liblapack.so.0 => /usr/lib/liblapack.so.0 (0xb732a000)
        libpython2.7.so.1.0 => /usr/lib/libpython2.7.so.1.0 (0xb71bb000)
        libc.so.6 => /lib/libc.so.6 (0xb7035000)
        libblas.so.0 => /usr/lib/blas/atlas/libblas.so.0 (0xb7014000)
        libcblas.so.0 => /usr/lib/blas/atlas/libcblas.so.0 (0xb6ff2000)
        libatlas.so.0 => /usr/lib/libatlas.so.0 (0xb6933000)
        libgfortran.so.3 => /usr/lib/gcc/i686-pc-linux-
gnu/4.5.2/libgfortran.so.3 (0xb6871000)
        libm.so.6 => /lib/libm.so.6 (0xb684b000)
        libgcc_s.so.1 => /usr/lib/gcc/i686-pc-linux-gnu/4.5.2/libgcc_s.so.1 
(0xb682d000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xb6813000)
        libdl.so.2 => /lib/libdl.so.2 (0xb680f000)
        libutil.so.1 => /lib/libutil.so.1 (0xb680b000)
        /lib/ld-linux.so.2 (0xb7891000)

So nothing from blas/cblas/lapack was linked into your scipy which is very 
worrying. It may be that there is a problem with your current blas&co setup.
what's the output of
ls -la /usr/lib64/libcblas.so
