(Read the update below before starting to copy-paste) To install Xhprof on PHP5.4 on Ubuntu (assuming you've already got PHP5.4 from Andrej or somewhere safe) in order to measure the load of Chamilo 1.10 dev (you need to have a mercurial clone, otherwise the "tests" directory will not exist), follow this procedure (all lines prefixed with # are comments): 
cd /tmp
sudo apt-get install php5-dev php-pear
