It looks to me like there is a numerical error in the gcc-4.3 compiled version
of sketch, which passes an IEEE NAN to printf.  I think it must be at least
partly an amd64 issue. I have not rebuilt the binary package with gcc-4.3 (needs
some chroot wizardry to get right), but

cd sketch-0.2.59
make CC=gcc-4.3
sketch -Dex070 ./Doc/manexamples.sk

works OK for me on i386 (i.e. no nan in the output).

It would be helpful if someone could try a gcc4.3 i386 build to narrow down the
possibilities.  I will do that as my next step if no-one reports anything 
before.
