I've used both, LuaD and DerelictLua + my own smaller D library 
that wraps all these nasty Lua stack operations (e.g. creating, 
accessing and adding to tables). The better I got to know the Lua 
C API while writing my own wrappers, the more I came to 
appreciate LuaD :-) However, LuaD is still 5.1 and I didn't want 
to be stuck with 5.1. So I rolled my own. It's not as 
comprehensive as LuaD but did the trick.

The purpose was to experiment with Lua server pages + vibe.d 
which worked fine. Rikki gave me the idea to compile each page as 
a Lua function into memory for faster execution (etLua style[1]). 
It works fine with both LuaD and my own wrappers. In my own 
version I use the Lua C API directly in some places, though I 
don't know, if that's really a big speedup.

If I set up my own homepage, I'd probably give vibe.d + Lua a 
shot. No more PHP and sh*t like that.
