How-to-build-toolchain.pdf - "chmod a+x ./debian/rules" fails

Hi,

I followed the "How-to-build-toolchain.pdf". When I execute "chmod a+x ./debian/rules" I receive: no such file or directory:

build@arm-desktop:~$ cd tools/
build@arm-desktop:~/tools$ ls
mingw32 mingw32-binutils mingw32-runtime
build@arm-desktop:~/tools$ cd mingw32
build@arm-desktop:~/tools/mingw32$ ls

build@arm-desktop:~/tools/mingw32$ cd mingw32-4.2.1.dfsg/
build@arm-desktop:~/tools/mingw32/mingw32-4.2.1.dfsg$ ls

build@arm-desktop:~/tools/mingw32/mingw32-4.2.1.dfsg$ chmod a+x ./debian/rules
chmod: Zugriff auf „./debian/rules“ nicht möglich: No such file or directory

What is my mistake? I followed the How-to step by step.
