[plt-scheme] List libraries - name collisions

According to the manual for v372,

I should be able to use both of the following lines:
(require (lib "list.ss"))
(require (lib "list.ss" "srfi" "1"))

because the names in the srfi version are supposed to be renamed to
avoid collisions.
But I'm getting an error, indicating that "third" and possibly other
functions are defined in both modules.

Is there something I'm doing wrong, or is this a bug?

Thanks,

Mark
