I think that GSL does not include linear programming solvers, but in the
GSL home page there is a reference to the GLPK package:
http://www.gnu.org/software/glpk/glpk.html
I have not used it, but it would be very nice to have a simple Haskell
interface to GLPK (or other similar library) in hmatrix or as a separate
package. I will take a look at this.

I have never used this part of hmatrix, but does
Numeric.LinearAlgebra satisfy your needs? In particular, see
linearSolve[1] and linearSolveR[2].
