Permission denied when I try to configure mcsdk OMAP-L138 in Linux

I follow instructions from http://processors.wiki.ti.com/index.php/MCSDK_OMAPL138_User_Guide_Getting_Started to install MCSDK OMAP_L138 Linux sources. But when I pass the step "Linux Host Setup" and run setup.sh script I've got an error:

tankist@ubuntu-12-04:~/ti/mcsdk_1_01_00_02$ sudo ./setup.sh
-------------------------------------------------------------------------------
TISDK setup script
This script will set up your development host for SDK development.
Parts of this script require administrator priviliges (sudo access).
-------------------------------------------------------------------------------
./setup.sh: 71: ./setup.sh: ./bin/setup-host-check.sh: Permission denied
Failed setup, aborting..

What the problem is?
