Apple has an entry for Lynx on their Download site.
It's easy to install with that download, and I've just confirmed that only five steps are needed to use it over Telnet:
1. Download from the link above.
2. Double-click 'install.command'
3. Type your user password
4. Enable "Remote Login" on the OS X machine in the "Sharing" Preference pane
5. Telnet in, then type "lynx"
(Note that OS X by default requires that you actually use the ssh protocol, not the older telnet protocol. this MacOSXHints article says how to enable plain-ol' Telnet, if your Telnet client doesn't support ssh. Although it looks like a simple "sudo service telnet start" is enough to do it, from comments to that linked article.)
In fact, I had typed this in Safari, but just copied and pasted the post into Lynx to actually post it.
