Hi Maurizio, first of all thanks for providing this :).
Now.. in the list of components you mention that you included openacs-5.4.3 ( CVS HEAD of 27/10/2008 ), if you took the core packages from HEAD on that date, then you have versions 5.5.*. If your intention was to provide openacs-5.4.3 then you should take the code from the tag openacs-5-4-3-final ( the same applies for dotlrn, the way to go should be using the tag dotlrn-2-4-1-final).Now with postgresql-8.3.0-2, the current stable release (openacs-5.4.3) doesn't fully support postgresql-8.3.* (HEAD version does) in this case, postgresql-8.2.* should be provided.
