Something's gone screwy in setting the path.  What you're echoing back
is the exact command that should have set it, not what should be the
contents of the variable.  I'd expect to see the error message

zsh: no matches found: /usr/lib64/lua/luarocks/share/lua/5.1//?.lua;/usr/lib64/lua/luarocks/share/lua/5.1//?/init.lua;/usr/share/lua/5.1//?.lua;/usr/share/lua/5.1//?/init.lua;/usr/lib64/lua/luarocks/share/lua/5.1//?.lua;/usr/lib64/lua/luarocks/share/lua/5.1//?/init.lua;/usr/share/lua/5.1//?.lua;/usr/share/lua/5.1//?/init.lua;./?.lua;/usr/local/share/lua/5.1/?.lua;/usr/local/share/lua/5.1/?/init.lua;/usr/local/lib/lua/5.1/?.lua;/usr/local/lib/lua/5.1/?/init.lua;/usr/share/lua/5.1/?.lua;/usr/share/lua/5.1/?/init.lua

if the variable LUA_PATH contains that value and the shell is attempting
to use it as a glob pattern.  You need to fix that before you'll get
a sane value.

Unless you have the globsubst option set, ?'s from a variable aren't
expanded.  If you do have globsubst set, which behaves like other
shells, you should probably set the option nonomatch, too, which doesn't
complain if the expansion fails.  Usually in zsh there's no reason to
set globsubst at all, however.
