This is a long shot, but is it possible that one of the earlier dirs in @INC has permissions that prevent perl from looking in it and is causing perl to terminate the search early?
Actually that is almost certainly the issue. The OP has /root first in the path which normally isn't accessible, and perl 5.18.0 onwards stops and errs on failure: 
$ perl5180 -I/root -Mstrict -e 1
Can't locate strict.pm:   Permission denied.
BEGIN failed--compilation aborted.
