phploc installation not working on ubuntu

I am trying to install phploc on my ubuntu 13.04 and it doesn't seem to
work here are the steps I followed.
sudo pear config-set auto_discover 1
sudo pear install phpunit/phploc

phpunit/phploc can optionally use PHP extension "bytekit" downloading
phploc-1.7.4.tgz ... Starting to download phploc-1.7.4.tgz (10,134 bytes)
.....done: 10,134 bytes
install ok: channel://pear.phpunit.de/phploc-1.7.4 .de/phploc
Then when i type phploc it givies this error <
br> $ phploc

/usr/share/php/SebastianBergmann/PHPLOC/autoload.php on line 44 PHP Stack
