Oracle OCI/Client install without OUI?

Hi, Does anybody have an idea on how I could install the oracle client/libraries required to build PHP with OCI support without using the OUI. The server is headless, and behind a firewalls, so X-Server is not an option, it also has no local CD-Rom, just to add to the problem. Platform := Solaris 8. I will attempt installing the client onto a similar machine, and extracting the components required to make a working client ?? but there must be a better way. Thanks in advance PaulB.
