That used to be a problem before luarocks, but now with luarocks you don't have to worry about it. You get fragmentation anywhere you go in every langauge no matter what. The problem in other "batteries included" languages is the core team dictate to everyone else the primary libraries, and then many times they refuse to update them and you have to work around them. In Lua, you don't have to do any of that. Lua gives you the kernel, then you add everything else you need.
