DPKG-DEB error

Hi I am trying to install a TI MultiCoreSDK for High Performance computing application. The installation script works on some .ipk files (unpacking and installing I assume). So when I run this script it shows me this error.

The instruction which runs inside the script is

sudo dpkg -x $ipk_install_path $destination_path

I am running on Ubuntu 14.04 LTS 64-bit flavor.

Installing ti-csl_git-r2_cortexa15hf-vfp-neon-3.8.ipk in to /evmk2h_nfs/
dpkg-deb: error: archive 'ti-csl_git-r2_cortexa15hf-vfp-neon-3.8.ipk' has premature member 'data.tar.gz' before 'control.tar.gz', giving up

Please let me know how can I fix these errors.

Thanks!
