Right. In my case it's rather the case that the build and distribution 
infra is *not* in place for my needs :-). Yes, it was definitely from 
the POV of power-users on HPC clusters who want to tinker with the 
build, not as wide reach as possible.

Well, in that case (and for the information of anybody else interested, 
Pauli already knows this), the fwrap-generated files from the SciPy .NET 
port may be a good starting point,
