where is Ghostscript 6.01

7.2 comes with ghostscript 5.5 while the info page tell you that 6.01 is newer and can be found on the ftp server. something about new licencing therefor its not on the distro set but on the ftp site. I have looke all over , does any one know where the 6.01 or higher of ghostscript version is ? I would like an rpm or binary rather than compile it. But if that is the last resort I will try it. Looks like it is needed for the lexmark Z23 but it was buried in the docs. thanks Samy
