Eigen BLAS

I've got a problem with the BLAS-Implementation of Eigen.
The two packages build without a hick but as soon as I try to use Octave an error comes up:
The LAPACK Function spotrf_ ist missing.

I spend some time trying to figure it out but without success...

Has somebody got Eigen BLAS to work and could help me out?
Thanks.

My PKGBUILDs:

pkgname=eigen3-blas
pkgver=3.0.1
pkgrel=1
pkgdesc="Eigen BLAS"
arch=('i686' 'x86_64')
conflicts=('blas')
provides=('blas')
url='http://eigen.tuxfamily.org'
license=('GPL' 'LGPL')
makedepends=('cmake' 'pkgconfig')
source=("http://bitbucket.org/eigen/eigen/get/${pkgver}.tar.bz2")
md5sums=('6259a841384b9e860939c4fd9181afb9')

build() {
    cd $srcdir
    mkdir build
    cd build
    cmake ../eigen-eigen-599fc4f7c736 \
        -DCMAKE_BUILD_TYPE=Release \
        -DCMAKE_INSTALL_PREFIX=/usr
    make blas
}


package() {
  cd "${srcdir}/build"
  make DESTDIR="${pkgdir}" install

  cd "${srcdir}/build/blas"

  install -dm755 $pkgdir/usr/lib
  cp -d libeigen* $pkgdir/usr/lib
  ln -s libeigen_blas.so $pkgdir/usr/lib/libblas.so.3
  ln -sf libblas.so.3 $pkgdir/usr/lib/libblas.so
  ln -s libeigen_blas_static.a $pkgdir/usr/lib/libblas.a
}

This is a slightly modified copy of the LAPACK-package  in extra.
