Just to give you a start, you might check out the nu blue book by Kim
Rose and Mark Guzdial, which has a chapter about writing primitives. It
won't help you with recompiling on specific platforms, but it will help
you with writing the primitives.
I haven't checked the websites, so can't help there.
In general, it's not the friendliest process possible, but at least
there *is* a process.
Also, you might check into Foreign Function Interface (FFI). Maybe you
can write your extension as a regular C function, and then call it via
FFI.
