Well, every implementation of Lisp does indeed contain an interpreter: eval!

But the way Lisp compilers deal with recursive macros is to not allow them. From the Common Lisp spec:

"All macro and symbol macro calls appearing in the source code being compiled are expanded at compile time in such a way that they will not be expanded again at run time."

That rules out recursive macros. I think they're allowed when Lisp is being interpreted, but you should probably just not use them.
