luaposix installs only posix.so, which is loaded by the standard loadall searcher, but
masked in the luarocks show output by posix/init.lua which provides the posix module.

Still can't reproduce it. I get the same output in a completely new docker container
(the easiest way to test on GNU/Linux from my Mac), with a fresh install of Lua 5.2.4
and no other Lua interpreters on modules anywhere else.

The home directory installation is because I lazily edited my luaposix .travis.yml
into a shell script to perform a source build and install of latest lua-5.2 and
luarocks-2.2.0. I then used that luarocks to install the latest luaposix rock from
the repo.
