Comment (by rhaas):

 On danger of being called out for me lack of wanting a fast LAPACK (this
 is realated to my general unhappiness with building everything from
 scratch since I have many compiled Cactus trees and many configurations
 and often compile new ones): I actually do "think that thorn OpenBLAS
 should use an installed, slow library instead of building an efficient
 OpenBLAS". At least in its probe-what-is-there mode. OpenBLAS may well
 want to output a warning, but otherwise I'd stick to: "the user installed
 the system LAPACK, so I use it". If they want to compile OpenBLAS then
 they can either uninstall the system one or ask for XXXX_DIR=BUILD. This
 is based on the notion that the OpenBLAS thorn provides the capabilities
 LAPACK and BLAS and is not only a wrapper around OpenBLAS's configure
 script.
