Found in openacs.org:/cvsroot/CVSROOT/modules:
(leaving lots of stuff out)
acs-core -a openacs-4/packages/acs-lang ...
So, I'm thinking that the line for the module acs-core should read instead, either
acs-core openacs-4/packages/acs-lang ...or
acs-core -a acs-lang ...
Could someone confirm this?
P.S: Bruno, could you try again without setting the directory?
Also note, that I'm getting weird directory structure when I try to check out openacs-core in this manner; rather than looking like an openacs server root, it looks like an individual package root.
