darwinports does a pretty good job. And for many things, the mac has better software available.

Besides "fake *nix" could apply as well to linux as to darwin. Remember that OS X actually licensed the Unix name...

No. You can compile the vast majority of unix projects on linux and run them with no modifications. Darwinports is ok if you want only the top 1% of popular projects, often several versions behind.
