Use of undefined constant FILE_TEXT

[twisen]

Hello,
I'm using your library join with symfony for my degree proyect (a bibliographic references manager). All works perfect but when I use a variable to call the function "parseFile" the page show me this:

( ! ) Notice: Use of undefined constant FILE_TEXT - assumed 'FILE_TEXT' in /home/sfprojects/UsalRef/lib/vendor/LibRIS/src/LibRIS.php on line 61

16 0.0533 1983232 LibRIS->parseFile( ) ../GestionRIS.php:385

I don't know why, When I use a string to pass the filename it's works perfect. My code is this:

public function executeFromRIS(sfWebRequest $request){
$RIS = new GestionRIS();
$RIS->importar('uploads/import.ris', $this->getUser()->getAttribute('UID'));

     //$this->redirect('referencia/index');
}

public function importar($archivo, $uid){
$ris = new LibRIS();
$ris->parseFile($archivo);

    $entradas = $ris->getRecords();
    $errores = 0;
    foreach($entradas as $index => $entrada){
        switch($entrada['TY'][0]){
            case('NEWS'):
            case('MGZN'):
            case('JOUR'):
            case('JFULL'):
                $errores += $this->risToArticle($entrada, $index, $uid);
                break;
            case('BOOK'):
                if(isset($entrada['PB'])) $errores += $this->risToBook($entrada, $index, $uid);
                else $errores += $this->risToManual($entrada, $index, $uid);
                break;
            case('PAMP'):
                $errores += $this->risToBooklet($entrada, $index, $uid);
                break;
            case('CONF'):
                if(isset($entrada['TI']))$errores += $this->risToConference($entrada, $index, $uid);
                else $errores += $this->risToProceeding($entrada, $index, $uid);
                break;
            case('ELEC'):
                $errores += $this->risToImproceedings($entrada, $index, $uid);
                break;
            case('CHAP'):
                if(isset($entrada['TI'])) $errores += $this->risToIncollection($entrada, $index, $uid);
                else $errores += $this->risToInbook($entrada, $index, $uid);
                break;
            case('THES'):
                if(isset($entrada['U4'])){
                    if($entrada['U4'][0] == 'master') $errores += $this->risToMasterthesis($entrada, $index, $uid);
                    else $errores += $this->risToPhdthesis($entrada, $index, $uid);
                }                   
                else $errores += $this->risToMasterthesis($entrada, $index, $uid);
                break;
            case('GEN'):
                $errores += $this->risToMist($entrada, $index, $uid);
                break;
            case('RPRT'):
                $errores += $this->risToTechreport($entrada, $index, $uid);
                break;
            case('UNPB'):
                $errores += $this->risToUnpublished($entrada, $index, $uid);
                break;
            default:
                $this->guardaError(sprintf("La entrada %s: %s no tiene un tipo reconocido.", $index, $entrada['T1'][0]));
                $errores += 1;
                break;
        }
    }

}

Thanks for the library at all and sorry about my english

What version of PHP are you using? (5.1, 5.2, 5.3?) I think the FILE_TEXT constant might not be defined in some versions of PHP.
