Error on `make menuconfig`: ~/Projects/local_buildroot/Config.in:1: can't open file "/Projects/local_buildroot/package/Config.in"

[lennybacon]

I followed the description and executed the following commands

mkdir -p ~/Projects/local_buildroot
cd ~/Projects
git clone git://git.buildroot.net/buildroot
cd local_buildroot
git init
mkdir configs package

echo 'name: LOCAL_BUILDROOT' > external.desc
echo 'include $(sort $(wildcard $(BR2_EXTERNAL_LOCAL_BUILDROOT_PATH)/package/*/*.mk))' > external.mk
echo 'source "$BR2_EXTERNAL_LOCAL_BUILDROOT_PATH/package/Config.in"' > Config.in

Inside my ~/Projects/local_buildroot directory I now have two empty directories (configs and package) and the three config files (external.desc, external.mk and Config.in). There are no files in the package directory.

Now I continue to run the commands documented.

git add *
git commit

cd ~/Projects/buildroot
export BR2_EXTERNAL=${HOME}/Projects/local_buildroot
make menuconfig

The output of the command make menuconfig gives me an error, complaining about a file it cannot open:

/home/df/Projects/local_buildroot/Config.in:1: can't open file "/home/df/Projects/local_buildroot/package/Config.in"
make[1]: *** [Makefile:992: menuconfig] Error 1
make: *** [Makefile:83: _all] Error 2

I definitively have not created the file inside the packages directory. The Config.in in the local_buildroot points to a file with the same name but underneath the package directory, which I created and is empty.

So where is the file ~/Projects/local_buildroot/package/Config.in supposed to come from? Am I missing something or is ther some step in the config missing?
