I've been following the Indigo tutorial from its beginning, without missing a step. For some odd reason, the beginner_tutorials package, that I created in tutorial 3, isn't recognized in tutorial 10 while typing:

$ rosmsg show <tab><tab>

It also doesn't show in

$ rospack list

one other thing that I've noticed is that the output while creating the package was different than that shown in the tutorial, e.g. there were no messages concerning GCC. This is the exact output:
