[plt-scheme] moshimoshi - Servlet didn't load. xxexpr.ss:23:2

While trying moshimoshi 0.7, I got

  Servlet didn't load. xxexpr.ss:23:2: module: identifier already imported
  (from a different source) at:
  reverse! in: (require (lib "1.ss" "srfi") (lib "13.ss" "srfi"))

when browsing

  http://duckfeet:8181/servlets/moshi-view.ss?page=MoshiMoshi

I saw no errors when starting moshimoshi
