GL VERSION error

Hi!
I have installed CUDA 4.0 (with SDK) on my machine -

Device 0: “Tesla C1060”
CUDA Driver Version / Runtime Version 5.0 / 4.0
CUDA Capability Major/Minor version number: 1.3

Then I have tried to run simpleGL program from SDK,
but I have got

ERROR: Support for necessary OpenGL extensions missing.

Further, by inserting of

printf ( “GL VERSION = %s\n”, glGetString(GL_VERSION) );

I’ve got

GL VERSION = 1.1.0

What is wrong in the environment on my machine and how to fix the situation?

Thanks.
Yury
