安装`phc` php编译器时无法安装包'libxerces27-dev` [关闭]

To install phc following this guide in Ubuntu Oneiric 11.04, I get error saying that the package is not available as below screenshot.

Searching for the package at ubuntu's package search page result in no luck for me.

It looks like ubuntu has changed since I wrote that. Try:

sudo apt-get install libxerces-c-dev

(Contributing the change to the phc documentation would be very welcome)
