aha, many thanks for the additional info! - seems that this is a bug in 
pdlua after all:

when pdlua loads a script it sets Lua's package path like this:

/* package.path := path .. "/?;" .. path .. "/?.lua;" .. package.path */

I'm not sure the best way to fix this, the standalone 'lua' interpreter 
doesn't mention .so in the package path at all:

Lua 5.1.3  Copyright (C) 1994-2008 Lua.org, PUC-Rio
 > print (package.path)

Any Lua experts know "the Lua way" to fix this?

I didn't notice it before because I got confused with another project of 
mine (not Pd related) - the complex-help.pd example loads a .lua 
package, not a .so package - sorry for the misleading information earlier.

Thanks again,
