You shouldn't need to untar it yourself or use "luarocks make" (which
is mostly a development tool). Simply calling

   luarocks install luarepl

should download and install it properly.

LuaRocks also installs a launcher for bin/ entries, and it takes care
of adding the proper call to the lua interpreter that it was
configured with, so no need to edit rep.lua.

In other words, don't use './rep.lua' from the tarball. This sequence
should work from a shell:

   luarocks install luarepl
   eval `luarocks path --bin`  # just in case it's not in your $PATH
   rep.lua

The rock does install all modules; Lua modules go to .../share/lua/5.1.
