1. Grab coreutils 5.2.1 from gnu.org and the debian patch from
http://packages.debian.org/unstable/base/coreutils
2. Extract the 2 dd patches which start with the line
+--- coreutils-5.0/src/dd.c.orig 2003-02-07 07:39:20.000000000 -0500
>
through, but not including, the line
>
--- coreutils-5.2.1.orig/debian/patches/19_ipv6
>
> You can see all the patch headers with
> zcat coreutils_5.2.1-2.diff.gz | grep '^---'
3. Get rid of the extra leading '+' (sed 's/^\+//'). You now have a working dd patch
4. Apply the patch and compile:
[tim@tim-linux ~/Kits]$ cd coreutils-5.2.1
[tim@tim-linux coreutils-5.2.1]$ patch -p1 < ../coreutils-5.2.1.dd-performance-counter.patch
