Just look through the install CDs for a file named lynx??????.i386.rpm
Log in as root and run this command:
rpm -ivh lynx?????????.i386.rpm
Which will install the package for you. Make sure to choose the rpm file which has "i386" in its name, and not "src". The package files with "src" install the source code for the program, and not the actual compiled executable binary files.
The lynx package on your RH7.2 CD is probably outdated by now. If you want the latet version, check out www.rpmfind.net
There are other console-based (text) HTML viewers/web browsers out there, and one of them is called "links". You can search for it at RPMFind as well.
