package php-intl does not exist on apt-get

following the instructions in the INSTALL file for Ubuntu distro, I discovered an error in one of the package names. php-intl does not exist, however searching the repo I found that a package named "php5-intl" does. I am only speculating that this package fulfills the same dependancies.
