trying to compile Attitude Adjustment from sources, and this error shows up after "make menuconfig"

Any suggestion where exactly "mips-openwrt-linux-uclibc-gcc" supposed to be ?

Where is it coming from ?

Do I need to download and install something else beside :

git clone -b attitude_adjustment git://github.com/openwrt/openwrt.git
git clone git://git.openwrt.org/12.09/packages.git
./scripts/feeds update –a
./scripts/feeds install –a

Thanks!
