trying to build on a system that needs buildtools does not work for fido using the latest buildtools (1.8.0m3). A python module seems to be missing.

buildtools downloaded from: http://downloads.yoctoproject.org/releases/yocto/milestones/yocto-1.8_M3/buildtools/poky-glibc-x86_64-buildtools-tarball-core2-64-buildtools-nativesdk-standalone-1.7.sh

Log:
