Created attachment 2863 [details] .config illustrating this problem. I tested this on 2010.11 and buildroot-20110117.tar.bz2, I tested this with a real external toolchain/powerpc but for the sake of the exercise let's do this as follows. Steps to reproduce: * Extract buildroot * make allnoconfig * In make menuconfig -> toolchain -> set toolchain type to external toolchain, save the config edb@lapedb:/tmp/tmp/buildroot$ make external-deps gcc-.tar.bz2 gmp-5.0.1.tar.bz2 mpfr-3.0.0.tar.bz2 edb@lapedb:/tmp/tmp/buildroot$ make source <snip> successful download of http://ftp.gnu.org/pub/gnu/gmp/gmp-5.0.1.tar.bz2 and http://www.mpfr.org/mpfr-3.0.0/mpfr-3.0.0.tar.bz2 </snip> mkdir -p /tmp/tmp/buildroot/dl --2011-01-17 12:58:19-- http://ftp.gnu.org/pub/gnu/gcc/gcc-/gcc-.tar.bz2 Resolving ftp.gnu.org... 140.186.70.20 Connecting to ftp.gnu.org|140.186.70.20|:80... connected.

Created attachment 2869 [details] Disable gcc fetch when not internal toolchain This is an old bug that's been lingering for some time now. Try the attached patch, it should solve the issue.
Tested on 2010.11, works there for me.
Committed a slightly revised version of the patch, which also disables the unneeded gmp/mpfr/mpc libraries, thanks.
