Yes it appears that you need to have the evaluation-portlet package installed. I can see that the code for it is in our CVS repository:
http://cvs.openacs.org/cvs/openacs-4/packages/evaluation-portlet/
Though someone may have packaged it up into an .apm file as well (I don't know).
It's a little odd that the package is referring to keys in a -portlet package. It's not unheard of for a package to borrow another package's keys, but usually the borrower is the -portlet.
