Hmm, I thought that sparse SVD was provided by ARPACK, already  
included in SciPy, and it was just a matter of writing the wrappers.  
Is that still the case, or is SVDPACK for some reason a substantially  
easier route/is SVDPACK better or more featureful?

That said: I think you're right about preferring SVDPACKC, Stefan.  
WIth all of the annoying issues surrounding Fortran compilers and  
ABIs, it seems to me that the less new Fortran code gets added to  
SciPy, the better.
