I was trying to intall metapict through the package installer and was getting the following error message

make-script: unexpected value rendered: '((font ((class "badlink")) (span ((class "indexlink")) (span ((class "RktModLink")) (span ((class "RktSym")) "metapict/draw")))))
  context...:

......

raco setup: error: during building docs for <pkgs>/racket-index/scribblings/main/user/search.scrbl
raco setup:   make-script: unexpected value rendered: '((font ((class "badlink")) (span ((class "indexlink")) (span ((class "RktModLink")) (span ((class "RktSym")) "metapict/draw")))))

drracket install: packages installed, although setup reported errors

Please guide me.
