Oh no.
Does that mean we can not integrate meschach into grass and only provide a
framework
or wrapper around it? And the user has to compile and install meschach by
himself
to run GRASS?

Or can we risk to integrate it. Because IMHO we have a lot of numerical
recipies code
in gmath which we need to replace.
But replacing one license violation with another is not such a good idea.

I have not the time and the knowledge to replace the numerical recipes
algorithm
with code developed by myself. :/
ATLAS does not provide such algorithms.
In case we choose BLAS, LAPACK, LINPACK and EISPACK
we will depend on a proper FORTRAN to C interface.

What can we do?
