How is the script installing them? Your best bet is to run
(you may need to do this as root).
Also running 5.8.0 seems like a bad idea. You should probably be running 5.8.x where x is the highest available number as this will contain a large number of bug fixes but will be "the same" as 5.8.0 . Apart from that, I don't know anything about CentOS or Apache's interactions with Test::Deep (I doubt it has any but some of the modules want it for testing).
