lynx and php, slightly OT

Sorry for the somewhat off topic post, but I'm running out of people to ask... I got a cronjob that performs this command: 30 * * * * /usr/bin/lynx -dump http://localhost/dir/build.php > /dev/null I changed my OS from FreeBSD 2.2.7 to RedHat 6.2 this past weekend, and now lynx is filling root's mailbox with error messages like this: Your terminal lacks the ability to clear the screen or position the cursor. And of course the job doesn't run. I tried adding -term=VT100 to the string but it didn't change anything. I also tried changing -dump to -source but that didn't work either. My build.php script is unchanged for several months now. Running /usr/bin/lynx -dump http://localhost/dir/build.php > /dev/null from the command line produces no errors. Any idea what I'm doing wrong? Thanks, Greg
