Version differences and other questions

[Kamek]

Ok I just got the book and did all the installation and everything.
Quickstarted me a project and it looks nothing like the one in the
book. Turns out I got tg 1.1b3, so what I'm wondering is what version
was used for the book. oes it matter? I got kid working and some of
the examples work but I get this error when trying to run the
Chapter5b example:

What version do I need to make the examples work, and how would I
uninstall my current turbogears stuff to install the right version, as
I didnt use virtualenv for this.
