The gsl gem has its issues (memory management and it can be kind of clunky to use sometimes), but it really does provide a great deal of numerical functionality.

Is the GSL itself somehow deficient for your needs?  It is also an open source project, so I'm (almost) sure patches would be welcome.  Ruby/GSL is also open source, though admittedly under-maintained. :-(

I agree that having numerical capabilities better supported would be a great thing, but I'm not sure that the Math module is the best place to do so.  There are so many things that could be added!  Where would it end? :-)
