The first time a user is required to "build" his or her OSS, will be the last time they use OSS. I don't understand why the linux community still thinks that it's appropriate to make end users compile their own software.
Photons travel at the speed of light and so by definition have zero mass. What they do have is an energy density, which our friend Dr. Einstein made sure to include in his GR equation. So if the universe was filled with nothing but photons, their combined energy density would create its own gravity. That being said, their combined gravity is predicted to be far less then what you need explain dark matter since the average energy of the photons in the universe is in the radio and microwave wavelengths.

...or will the simulated people just go about their lives not knowing the difference?
No need for Nature, you can read the preprint at: http://lanl.arxiv.org/abs/0704.2529
