I am seeing problems on SVD, possible related to LAPACK and friends. I get an error depending on the shape of the matrix given to svd, and 2xN's bomb out, while Nx2's seem to do fine.

This error is also occurring in the qp() function, but I assume because it is calling SVD

It may very well be due to my LAPACK installation, but I don't know how to determine that.
