Comment (by hamish):

 ''really'' dumb and inefficient emergency workaround:
  * g.region rows=1 cols=1
  * r.in.xyz x=1 y=2 z=1 out=x_mean
  * r.univar x_mean
 etc

 or just use v.out.ascii + awk.
 see this script for calc'ing the mean:
   source:grass-addons/vector/v.points.cog/v.points.cog

 that script could probably get a flag to also output numbers for
 variance,stddev without too much work.
