64-Bit Linux Support

Unable to compile extension on 64-bit Linux/Python

Is this a limitation of the original Box2D API, or a problem with the Box2D
interface assuming only 32-bit Python?

What version of the product are you using? On what operating system?
2.0.2b1

Please provide any additional information below.
