Looks like Al went to the current OpenACS docs whic, of course, contain all openacs packages on the 5-2- branch where the install docs under the "dotlrn" pakcage are totally out of date.
If he had visited openacs.org/projects/dotlrn/ he would have found more recent docs. It looks like dotlrn was never merged from 5.1 to HEAD ages ago.
