+# This PortGroup sets up variants for serial linear algebra (Accelerate/ATLAS/OpenBLAS/OpenBLAS-devel).
+#
+# Usage:
+#
+#   PortGroup               linear_algebra 1.0
+#
+#   in pre-configure, a line like this may be needed:
+#   configure.args-append --with-blas="-L${prefix}/lib ${linalglib}"
+#
+#   If +threads and +atlas are set, the threaded ATLAS library will be used.
+#
+
+# scalapack.
+# vecLibFort only needed if calling Accelerate from Fortran.
+# enforcing +lapack for OpenBLAS can be optional.
+
