Yocto using external toolchain encounter external_linaro_toolchain_version_handler error

Question

I use a external pre-build binary toolchain got from freescale, and follow the instructions list in linaro wik. Follow that directions, I add the meta-linaro(master branch) layer to my conf/local.conf in front of the openembedded/meta layer, and add the EXTERNAL_TOOLCHAIN and TCMODE GCCVERSION variable as below:

GCCVERSION = "linaro-4.6"
SDKGCCVERSION = "linaro-4.6"

EXTERNAL_TOOLCHAIN = "/extdisk/yocto/88/arm-fsl-linux-gnueabi/4.6.2"
TCMODE = "external-linaro"

IMAGE_LINGUAS = ""
LIMIT_BUILT_LOCALES = "POSIX"

DEFAULTTUNE_qemuarmv7a = "armv7athf-neon"

And my toolchian version detail information is:

Using built-in specs.

When I using bitbake -v core-image-minimal to build image, error occurs:

$ bitbake -v core-image-minimal

I don`t know what's going wrong, can anyone help me?

I was getting a similar message

It turned out it was the very last error that was the cause of my problems... I needed to install the ncurses libs

Your output has one line that might be the issue

ERROR: Layer 'linaro' depends on layer 'networking-layer', but this layer is not enabled in your configuration
