There are a lot of programs that will run under WINE (a windows compatibility layer) as well. Programs run under WINE are sometimes a little buggy and don't always work perfectly, but it's a non-emulation solution that has no performance penalty and can be used to get a lot running under Linux. It's pretty neat.

Apparently they have a mac version as well. I run into this from time to time on my Mac as well.
