I have a similar problem:

PHP Warning: require(Mutagenesis/FUTException.php): failed to open stream: No such file or directory in /usr/local/lib/php/Mutagenesis/Loader.php on line 135

PHP Fatal error: require(): Failed opening required 'Mutagenesis/FUTException.php' (include_path='.:/usr/local/php:/usr/local/lib/php') in /usr/local/lib/php/Mutagenesis/Loader.php on line 135
