Maybe I'm missing something from just skimming this long discussion, but
what about

  (random:normal)

(at the guile prompt)?

That's a distribution centered at 0 with sigma 1. I assume you know how to
shift it and scale it. If you're curious how to get it from a uniform
distribution, have a look at libguile/random.c.

Best regards,
Mikael
