ARPACK-NG is a collection of Fortran77 subroutines designed to solve
large scale eigenvalue problems.

This is a fork of ARPACK that is actively maintained.  As such, this
package will conflict with the ARPACK package.  Do not install both.

This requires a BLAS/LAPACK implementation.  Choose one of these
package sets:
 * OpenBLAS (includes both a BLAS and a LAPACK implementation)
 * atlas (includes both a BLAS and a LAPACK implementation)
 * blas, lapack (the Netlib reference implementations)
If more than one set is installed (assuming there are no packaging
conflicts) then the auto-detection will use the first implementation
from this list that it finds.  If in doubt, choose the Netlib
reference implementations; other packages that require a BLAS or
LAPACK implementation may not build if they are not configured to
detect/use alternate implementations.

If the `make check` command fails, try switching to the Netlib
reference implementations, or comment out that command at your own
risk.
