Squid Starting Problem

Having upgraded our Suse box to V9 (new install) and re making Squid/2.4.STABLE7 we can only run squid from the supplied script in the \bin folder, If we try say -k rotate . we ge a message to say that it canot find Squid! This is the same in root, either from the commad window with the path set to \sbin or by clicking the icon in \sbin! Any ideas anyone? Kind regards Adrian
