The upcoming lapack64 needs the library name liblapack64, the
variable for that was missing in the patch. This does not change
the build of math/lapack itself.
This was lost on the recent rework of the patches:
On NetBSD.
In PKGSRC_FORTRAM=gfortran case, libcblas has no RPATH=/usr/pkg/gccXX/lib
and libgfortran and libquadmath are not found.
In PKGSRC_FORTRAN=g95 case, libcblas has no
RPATH=/usr/pkg/lib/gcc-lib/x86_64--netbsd/4.1.2 and libf95 is not found.
Use Fortran compiler as linker instread of C compiler to fix link.

Install the new interchangeable BLAS system created by Thomas Orgis,
currently supporting Netlib BLAS/LAPACK, OpenBLAS, cblas, lapacke, and
Apple's Accelerate.framework. This system allows the user to select any
BLAS implementation without modifying packages or using package options, by
setting PKGSRC_BLAS_TYPES in mk.conf. See mk/blas.buildlink3.mk for details.
This commit should not alter behavior of existing packages as the system
defaults to Netlib BLAS/LAPACK, which until now has been the only supported
implementation.
Details:
Add new mk/blas.buildlink3.mk for inclusion in dependent packages
Install compatible Netlib math/blas and math/lapack packages
Update math/blas and math/lapack MAINTAINER approved by adam@
OpenBLAS, cblas, and lapacke will follow in separate commits
Update direct dependents to use mk/blas.buildlink3.mk
Perform recursive revbump
Have switched to the CMAKE build and enabled tests.
make test passes all (with one patch pushed upstream)
Package additions, from the release notes are:
LAPACK 3.9.0
LAPACK QR
preconditioned QR SVD method for computing the SVD with high accuracy,
by Zlatko Drmac
LAPACK Householder Reconstruction
by Igor Kozachenko and Jim Demmel
LAPACK 3.8.0
Symmetric-indefinite Factorization: Aasen’s tridiagonalization 2 stage
A contribution from Ichitaro Yamazaki (University of Tennessee).
LAPACKE interfaces
A contribution from Julie Langou (University of Tennessee).
* Linear Least Squares / Minimum Norm solution
* Symmetric-indefinite Factorization: Aasen’s tridiagonalization
* Symmetric-indefinite Factorization: New storage format for L factor in Rook Pivoting and Bunch Kaufman of LDLT
* Symmetric eigenvalue problem: Two-stage algorithm for reduction to tridiagonal form
* Improved Complex Jacobi SVD
* LAPACKE interfaces
LAPACK 3.6.1: What’s new
[Mark Gates, UTK] blocked back-transformation for the non-symmetric eigenvalue problem
It blocks NB gemv calls into one gemm call inside trevc. To do
that, it needs a new routine, trevc3, because unfortunately the
lwork was not passed into trevc. Attached is the performance speedup
for dgeev. It gives a nice 1.5x speedup for N=20000, and that
appears to still be increasing with N. This is not the improvements
that Greg Henry recently provided for doing the triangular solves
as BLAS-3 instead of BLAS-1. That will take a while to process,
but we expect another, even larger increase in performance when
those changes are applied. This also does not include doing multiple
(BLAS-1) triangular solves in parallel, which is available in MAGMA,
since that requires OpenMP or pthreads.
* added Symmetric/Hermitian LDLT factorization routines with rook pivoting algorithm
* 2-by-1 CSD to be used for tall and skinny matrix with orthonormal columns (in LAPCK 3.4.0, we already integrated CSD of a full square orthogonal matrix)
* New stopping criteria for balancing.
