If your system is Linux/Redhat, you have to use the command rpm -i package-name.
If your system is Linux/Debian, you have to use the command dpkg -i package-name.
If your system is not a Linux one, you have to get and install the source of ivy-perl. In this case, you have to get the source from CENA at http://XXX or from one of the Fairway sites.
