It isn't normal.
I've tried it just now, on a fresh install of 13.2.3 on XO-1.75, and
there are no such messages.
The Wiki page is fine.
You've probably made a mistake in copying and pasting the command, see
http://wiki.laptop.org/go/Compound_commands for help in pasting.
An alternative?
Is it normal that the following command fails with a series of no such
file or directory messages?
Here's the command suggested by

sudo yum localinstall -y \
