cc2530 cannot build hello world

just git clone from git clone https://github.com/contiki-os/contiki

then build hello -> make TARGET=cc2530dk hello-world

but it show me:

~/tmp/build/contiki/examples/cc2530dk(master) » make TARGET=cc2530dk hello-world                                                                                                                                                                marco@thinkPad
