Hi Liam,
Yeah, well the clbuild instructions *used* to be on the web page, but I took them out because of all the changes, and I just figured I'd get the clbuild people to add appropriate lines. That didn't happen in turn because I can't figure out how to make a darcs diff which is how they take all patches.
I've generated a darcs diff from the stock clbuild. It's attached in case that is helpful. The command that I used was "darcs send -o gsll-clbuild.patch".
