shoggy24, what exactly did you try to run?
the utility is /usr/local/psa/bin/sitebuilder, so you have to insert "/usr/local/psa/bin/sitebuilder --help" to run it.
yopade in his reply already was in /usr/local/psa/bin directory, that why he had to type "./sitebuilder --help" to run command from current (.) directory.
