Scipy Lapack problems

In a cluster, it cannot find our Lapack and also it doesn't set rpath, so the lapack and blas are not found at runtime. This PR should fix it.

TODO:

* [ ] Test it
* [x] Try to remove the Lapack rpath option (`-Wl,-rpath=$LAPACK/lib`), maybe it will set it automatically (result: it won't)
