Do you have a blas + lapack install? Unfortunately the error message "OpenBLAS or Netlib BLAS/CBLAS is required on all platforms except Windows, and was not found" is incorrect as a blas install is required on all platforms.

Oh also we don't have the wheels published for 3.13 yet I think, it's on my todo list!
