I tried to update Joomla from my current version 1.5.8 using com_updater and I get the following error, any thoughts?

Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set in /home/bobausa0/public_html/administrator/components/com_joomlaupdater/admin.joomlaupdater.php on line 147
Operation completed without any errors with curl functions.
Joomla_1.5.0_to_1.5.11-Stable-Patch_Package.zip was used for updating joomla core.
There was a problem updating joomla to the latest version
