Hello, I would welcome your help with fixing rng issues. We don't currently have a GSL developer with expertise in rngs (I myself have never worked on them). The best approach would be to clone the git repository (instructions on the GSL webpage), make your changes, and then send me a git diff when ready. Then I can take a look at things.
