 On a modern, package-based operating system such as Debian, you can
 install all of the dependencies with the following simple command
 line:
 
-	sudo apt-get install libxapian-dev libgmime-2.4-dev libtalloc-dev
+	sudo apt-get install libxapian-dev libgmime-2.4-dev libtalloc-dev libz-dev
 
 On other systems, a similar command can be used, but the details of the 
 package names may be different, (such as "devel" in place of "dev").
