Did you drop the original database and recreate an empty one
before your reinstalled the alpha release? That is my first guess
as to why it failed for you.
In other words, use "dropdb openacs4" then redo the "createdb"
and "createlang" steps.
Also note that you will have to visit /acs-admin/apm/ after your
install to load any none acs-core packages as an additional
step.
