Running cloudfront/processqueue generates an error, "CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in ... "

I have safe_mode off, but open_basedir is set for purposes of security. Is there a way to make the module work, with open_basedir set? (I've found lots of notes on this error message, but nothing clear on how to address it safely, without turning off open_basedir.)

Note: When I set the "add to Cloudfront" action in the imagecache setting, it does send the scaled/cropped version of the druplicon to Cloudfront, so the other settings appear to be working, but no actual imagecache images are sent on cron; just generates the error. Thanks!
