This thread in the mailing list archive solves a similar problem:

You can try the following script to generate a bytecode file of all
the listed modules (see the beginning of the script). Then in your
final program, just call dofile("preload.lbc") before using (through
'require' as usual) any of your modules.

local modules = {

local preload = ""
for _,modname in ipairs(modules) do
	preload = preload .. 'function package.preload["'..modname..'"](...)' .. '\n'
	preload = preload .."%.", "/")..".lua"):read"*a" .. '\n'
	preload = preload .. 'end' .. '\n'

local output ="preload.lua", "w")

os.execute("luac -o preload.lbc preload.lua")
