 But there's some more things we can do to improve \code{bar}'s
-packaging. If you go to \code{output/build/bar-1.0} and run
+packaging. If you go to \code{output/build/bar-1.1} and run
 \code{./configure --help}, you will see that it supports a
 \code{--with-libconfig} option. And indeed, \code{bar}'s \code{README}
 file also mentions \code{libconfig} as an optional dependency.

 It fails to build with messages like \code{error: unknown type name
 ‘config_t’}. Seems like the author of \code{bar} messed up and forgot
 to include the appropriate header file. Let's try to fix this: go to
-\code{bar}'s source code in \code{output/build/bar-1.0} and edit
+\code{bar}'s source code in \code{output/build/bar-1.1} and edit
 \code{src/main.c}. Right after the \code{#if defined(USE_LIBCONFIG)},
 add a \code{#include <libconfig.h>}. Save, and restart the build of
 \code{bar}. Now it builds fine!
