I think you should have installed all recommended dependencies: this is
how the book is tested. Without knowing what you have *not* installed,
it is hard to debug (reproduce) your problem.

It may mean that some other package is lacking X11 support (according
to the error message in the log), while xfce4-session has it. Or X11
support is compiled in for xfce4-session, but some dependency is
missing to make use of it.
