cl-redis problems

Hi, I've been using cl-redis with ecl without problems, but recently i have some trouble when installing on new systems. rutil is a dependency installed by quicklisp when doing quickload on cl-redis, and i've been getting: "There is no method on the generic function PRINT-OBJECT that agrees on qualifiers NIL and specializers (HASH-TABLE T)" This is the ecl that's installed via apt-get, ecl-13.5.1. I did notice that sbcl finds the method correctly when doing "(find-method #'print-object nil '(hash-table t))", while ecl also gives the error above. Any idea on how to further investigate this? Thanks in advance!
