Yes, the official LuaRocks repositories contain only source rocks (not
binary rocks) for Linux.
I don't know how things work in the recent Ubuntu, but in my system I
just built Lanes with LuaRocks and I have libpthread.so.0 listed in
the output of `ldd lua51-lanes.so` (and I did spot "-lpthread" in the
gcc command during compilation).
You may want to try to `luarocks remove lanes` and then `luarocks
build lanes` again and see if you notice anything strange.
