Forum OpenACS Development: couldn't execute "psql": no such file or directory

in attempt to have a fresh installation of oacs 5.4,
i have got the error message bellow. I debugged the file
/usr/local/aolserver/servers/projop/packages/acs-bootstrap-installer/installer/install.tcl
but i haven't found any reference to psql

does anyone already got into this issue?

I am using daemontools I and got a bit confused here starting aolserver directly with aolserver/bin/nsd instead of nsd-postgres
