I suspect the configure.zcml itself isn't being parsed. An easy, crude 
way of figuring this out is to introduce a syntax error. Change that 
line to read:

<include package=".browser

i.e. leave it with an unclosed string and an unclosed tag. If Zope fails 
to start up, then there's something else wrong. If Zope starts up 
correctly, then this file isn't being loaded, which explains why it's 
not finding the registrations.

I'm not sure which part of the book you're in, but you may want to try 
to put a file in etc/package-includes called e.g. test-configure.zcml, 
and have it include:

  <include package="my.package" />

where my.package is the name of the package you're currently in.
