This is just not true. Libpng is not required to build Cairo. It may be foolish to build without it, which is why it was recommended. Saying that Libpng is required to build Cairo is a lie. For example, suppose that someone decided to build Gobject Introspection in chapter 6 of LFS, before they compile Udev. Gobject Introspection will complain the Cairo is not installed and make you pass --disable-tests to configure. If you wanted too you could install a stunted version of Cairo just so Gobject Introspection can run its tests. Saying that Cairo requires Libpng would make them install Libpng too in a situation where it's not needed. Putting incorrect statements into the book makes it worse. The book should give people information. Putting false statements into the book makes it worse.
