Could it be that there's a problem with repository permissions?
I am trying to cvs checkout from HEAD several modules, some work, others don't.
Modules I can checkout include: ajaxhelper, acs-tcl, acs-datetime, etc.
Trying to check out acs-bootstrap-installer, I get a:
cvs server: cannot find module `acs-bootstrap-installer' - ignored
cvs [checkout aborted]: cannot expand modules
