 either ~/.profile or ~/.bashrc:
 
 if [ -e /usr/pkg/bin/z.lua ]; then
-	eval "$(lua /usr/pkg/bin/z.lua --init posix)"
+    eval "$(lua ${PREFIX}/bin/z.lua --init posix)"

 Then, as z.lua learns your habits, you may use the following
 command to quickly jump around your filesystem:
-    $ z SOME_DIRECTORY
+    z SOME_DIRECTORY
 
 z.lua also has explicit support for other shells, so
 you may want to consider replacing the `--init posix'
