Server Mx-Graphs config

[whortas]

Try to put this working in a PI and something is missing...
First I think that is something with Apache2 but I try Ligthtpd and I got the same error.

I have a test.php and work , so I presume that is not problem of permitions.

<?php
// Change this defines to where Your fonts are stored
DEFINE("TTF_DIR","/var/www/jpgraph/fonts/");
// Change this define to a font file that You know that You have
DEFINE("TTF_FONTFILE","DejaVuSans.ttf");

$f = TTF_DIR.TTF_FONTFILE;
if( file_exists($f) === false || is_readable($f) === false ) {
echo "FAIL: Can not read font file \"$f\".";
}
else {
echo "PASS: Successfully read font file \"$f\".";
}
?>

The GD and FreeType is available in the server like is show in phpinfo
