Mr. Gopal, To use manufacturer's component/footprint libraries imported into Protel is quite misleading for any board designer. One should always get the latest footprint from the manufacturer and use Protel to create the footprint. If you are rushing to finish a project and are using outdated footprints from the component libraries provided by Protel then good luck.
Here is a link for the Atmega169 chip. http://www.atmel.com/dyn/resources/prod_documents/2514S.pdf The package and footprint land pattern is on page 15 to page 18.
