The package is designed to compute a few eigenvalues and corresponding 
eigenvectors of a general n by n matrix A. It is most appropriate for large 
sparse or structured matrices A where structured means that a matrix-vector 
product w <- Av requires order n rather than the usual order n2 floating point
operations. This software is based upon an algorithmic variant of the Arnoldi
process called the Implicitly Restarted Arnoldi Method (IRAM). When the matrix
A is symmetric it reduces to a variant of the Lanczos process called the 
Implicitly Restarted Lanczos Method (IRLM). These variants may be viewed as a
synthesis of the Arnoldi/Lanczos process with the Implicitly Shifted QR
technique that is suitable for large scale problems. For many standard 
problems, a matrix factorization is not required. Only the action of the matrix
on a vector is needed.
ARPACK software is capable of solving large scale symmetric, nonsymmetric, 
and generalized eigenproblems from significant application areas. The software
is designed to compute a few (k) eigenvalues with user specified features 
such as those of largest real part or largest magnitude. Storage requirements
are on the order of n*k locations. No auxiliary storage is required. A set 
of Schur basis vectors for the desired k-dimensional eigen-space is computed
which is numerically orthogonal to working precision. Numerically accurate 
eigenvectors are available on request.

- Use a static header file instead of generated by f2c.
  It decreases a dependencies and so fix build on 7.0.

Make math/arpack depend less on math/atlas

        Atlas is great in the platforms where it's available, however
        it is not being packaged (for good reasons) anymore. arpack
        originally used blas for testing and since we are not really
        linking any version of blas in the package it doesn't make
        any difference what we use. It seems better idea to use
        blas for testing since it's faster to build and because
        this also means we can package arpack without building
        ATLAS, The resulting package will work with BLAs or ATLAS
        just the same and in any case the BLAS_LIBS variable can
        now be overridden to test with atlas if it's so desired.

        This change doesn't change the package so I think we should
        leave the PORTVERSION untouched.
