Unfortunately this is because the LuaRocks maintainers don't understand
how to build shared objects properly.  They added a *HACK* to enable
-fPIC on systems which ident as x86_64, but they are refusing to accept
(or perhaps to acknowledge) that actually *all* platforms require -fPIC
in order to operate properly.

If you installed LuaRocks from source then it will likely function for
you, albeit badly and hackily.  If you installed from a packaged
version then it's possible that your distribution built once on one
platform not realising that this idiocy would ensue.  If this is the
case then you're probably a bit stuck.  You could try poking at
luarocks/cfg.lua and see if you can persuade it to override the
defaults.

Regards,

Daniel.
