I've been using gsl in my personal patch for a long time, linking the
gsl and gslcblas shared libraries.  It works fine for me, and is within
a few parts per million of what R calculates -- good enough for
bogofilter.  I had assumed we wouldn't want to force that rather bulky
library on folks who don't do any other numerical analysis type stuff,
but I didn't quite have the nerve to try to pull out the code we'd need
in bogofilter.
