Guiallumes link looks to be for integer programming, not floating point 
calcs.  LAPACK or something that wraps it is what you want.

I highly recommend you look at the BLASLAPACK dir of 
dsource/projects/multiarray.  The LAPACK wrappers have been tested on 
both Windows and Ubuntu.  I have instructions in both dirs for how to 
install in either case, and there's a simple test program there that 
does a linear solve on a small matrix.

http://www.dsource.org/projects/multiarray/browser/trunk/multiarray/BLASLAPACK/lapacktest.d

The blas and lapack are separate from the rest of multiarray, so you can 
just check out that BLASLAPACK dir and be good to go.
