Sparse matrix solver libraries

[Vic Kelson]

Hi All.

OK. I'm sold on using D to develop an experimental hydrologic 
modeling code, but I need a sparse linear algebra package. Has 
anyone either developed such a package in D or linked to an 
existing C or C++ library? There are a number of existing free 
libraries out there, and I hate to reinvent the wheel. If no such 
D library interface exists, I'm happy to work on one as a 
community project, but I suspect I'll need quite a bit of help. 
Is anybody game for such a project?

THANKS!
