Rather than looking for a specific module to redirect a your error and warnings, why cant you simple write a small module which redirects your STDERR and STDOUT to a log file. tie that module in your program.

Is my suggestion acceptable. Because i did this way and i find it very useful and handy because i can tune accordingly to my need.

A small psuedo code for you...it will be help full..i think..

sub setlog {
          unless( ($log = tie(*STDOUT, 'your::module', ">>$LOGFILE")) 
+) 
}
--------------
your::module
-------------
sub PRINT {
    $fh # file handle
    my $line = (caller(0))[2];
    syswrite $fh, sprintf("[ %-18.18s %s %4.4s ] %s %s", "$script $lin
+e",
 }
