Michael,
Unless you need the i18n work you should check
out the oacs-4-6 branch of OpenACS and the dotlrn-1-0 branch
from dotLRN. If you do you need to get i18n stuff, then make sure the checkout if from HEAD of both dotLRN and OpenACS.
As it stands, the 4.6 branch of OpenACS does not provide the
acs-lang stuff that dotLRN HEAD requires.
