Yes, require from Lua doesn't know where the .pd_lua file was loaded 
from.  I'll have to research if it's possible to work like you suggest - 
I guess before running the .pd_lua script I could add the path to Lua's 
path then remove it again after it's loaded.

There is support for one-off execution of .lua scripts found via Pd's 
path (relative to the object instance, not the original source file), 
use it like self:dofile("myscript.lua").

Alternatively, you could make mylib.pd_lua that registers multiple 
objects and contains the common support code, and use it like:

pd -lib lua -lib mylib

Neither of these are ideal, though.
