When using Lynx at cron to do various automated data pulling tricks, lattest slang library (we presume that is the problem) barfs that the process has no controlling tty. For example following: TERM=dumb lynx -dump http://whereever/whatever used to work -- at 5.2 very least, but 6.2 barfs nastily. Why we DON'T use e.g. wget ? Lynx supplies us with rendered version of the page so we don't need to parse HTML tags ourselves, nor be that susceptible for changes at the HTML source as long as the rendered result looks vaguely alike.
I can reproduce this on 6.2, but not on 6.1 or on the public beta. I'm going to mark it as currently fixed; I'd suggest grabbing slang-1.4.1 (or possibly the latest lynx) and rebuilding it on 6.2; it shouldn't cause a problem.
