glibc-2.3.2.ds1 source not building

[NZG <ngustavson@emacinc.com>]

I'm trying to build
glibc_2.3.2.ds1-22sarge3
from source, but it's failing

I do this:
wget 
http://ftp.debian.org/debian/pool/main/g/glibc/glibc_2.3.2.ds1-22sarge3.dsc
wget 
http://ftp.debian.org/debian/pool/main/g/glibc/glibc_2.3.2.ds1-22sarge3.diff$
wget 
http://ftp.debian.org/debian/pool/main/g/glibc/glibc_2.3.2.ds1.orig.tar.gz

dpkg-source -x glibc_2.3.2.ds1-22sarge3.dsc
cd glibc-2.3.2.ds1
fakeroot debian/rules binary

And I get this:
test -d /home/nathan/workspace-new/crosstool/glibc/glibc-2.3.2.ds1/stamp-dir/patched || 
install -d /home/nathan/workspace-new/crosstool/glibc/glibc-2.3.2.ds1/stamp-dir/patched
applying patch debian/patches/10_cvs.dpatch... failed.

What am I missing here?

thx,
NZG
