Error running Squirrelmail: Warning: stat failed for functions (errno=2

Hi guys... I'm trying to install SquirrelMail for the 1st time... I unpack the .tar.gz file and move it to the DocumentRoot for the Apache Virtual Directory, run the /virtual_directory_document_root/squirrelmail/config/conf.pl set all the variables to use the uw IMAP Server. and try to log http://www.mydomain.com/squirrelmail/ I type a valid username/password and after I click on the login Button I get the error message: Warning: stat failed for functions (errno=2 - No such file or directory) in /Websites/www.jmvtec.com/squirrelmail/functions/display_messages.php on line 50 I try searching for that err on the docs but no luck on that. Any clue ? Thanks in advance !! bye --ed
