hi,
well, the only lynx that i am aware of is a terminal based web-browser...
if, however, you are speaking of some application which used the standard apple installer, and so has left a package in the /Library/Receipts directory, there will be a file somewhere within that package with the extension of ".bom" (often, but not always, the file is called "Archive.bom"). this is a bill of materials file which you can view using the terminal command "lsbom". have a look at the man page.
cheers,
