The defvar is only executed at run time (although it does have an
effect at compile time, which is to tell the compiler that the variable
will exist at run time).

So using `ll' during the macro expansion is wrong.

If you want `ll' to defined earlier, you can wrap it in
`eval-and-compile' (tho it's better not to abuse it).  I can't tell what
solution I'd recommend in your case, since your distilled test case is
"too distilled" to understand what it's trying to do.
