The official MacFUSE release doesn't work under 64bit kernels and the original maintainer hasn't touched the code in a while. Fortunately, the source code needed only two minor changes and then I was able to compile it under Snow Leopard. You can get the source from my github repository. For your convenience I've also built a package, you can get it here. DISCLAIMER: Use at your own risk, I'm not a Mac developer, I know nothing about the Darwin kernel. If it makes your computer explode, don't hold me responsible!
