Sure. If you create an empty environment and then invoke macros that
generate calls to functions not in that environment, errors are exactly
what you should expect. In this case, the macro "quasiquote" generates
calls to the function "##sys#list":
#;6> (macroexpand '`(1 2 ,x))
(##sys#list (quote 1) (quote 2) x)
