GSL is written in C, and I don't know any language more portable than that! gsl_vector and gsl_matrix use a continuous block of doubles, so you can use the FFI to marshall this however you want for efficiency.
I'd stick with GSLHaskell until you're ready to optimize the data marshalling though.
I like spending my time on interesting things, not reinventing pre-debugged and efficient libraries. I use GSLHaskell in my work and have never had a problem.

That's my preference, too. Have you ever tried GSLHaskell on MS Windows? I do most of my work on Linux, but a guy I'm working with uses MS, and I've heard cygwin can be a huge pain. I have a big space leak right now I thought might be because of list laziness in the interface, but that should be squashable with a little work, and is not as big a deal as having lots of dependencies when passing code around. I only really need one function from GSL, and the odds of someone having written a work-alike in Haskell seemed pretty good. Of course, in cases where GSL is already installed, or where more of its functionality is needed, GSLHaskell is the obvious choice. Chad
