SGX demo application run error on BB

Hello,
        I have installed latest codesourcery lite toolchain and
compile sgx demo application (OEGLS).I got error:

PVRShell: EGL 1.4 initialized
Exit message has been set to: "PVRShell: Unable to create surface
".
InitAPI failed!
PVRShell: Unable to create surface

I have followed all steps as per this link :
http://wiki.davincidsp.com/index.php/GSG:_Rebuilding_the_Software

I have used Angstrom latest demo image.
