$ ll /usr/lib/libcblas.*
lrwxrwxrwx 1 root root 25 Jun 10 20:57 /usr/lib/libcblas.a ->
blas/reference/libcblas.a
lrwxrwxrwx 1 root root 26 Jun 10 20:57 /usr/lib/libcblas.so ->
blas/reference/libcblas.so
lrwxrwxrwx 1 root root 28 Jun 10 20:57 /usr/lib/libcblas.so.0 ->
blas/reference/libcblas.so.0

I think its installed correctly,

$ nm /usr/lib/libcblas.*  | grep cblas_ddot
cblas_ddot.o:
00000000 T cblas_ddot
nm: /usr/lib/libcblas.so: no symbols
nm: /usr/lib/libcblas.so.0: no symbols
