unable to run bash build-tool-chain -m tx6 -pg

[chronosito]

Hi,
I am newbie here and I want to build a linux OS to flash TX6U-8130.
after runing make ARCH=arm tx6_defconfig to create a default .config file for the kernel, I need to build the tool-chain for i.mx6 by executing bash build-tool-chain -m tx6 -pg , but I get this:
