lifted from compat-5.1:

--
-- looks for a file `name' in given path
--
local function findfile (name, pname)
        name = gsub (name, "%.", LUA_DIRSEP)
        local path = _PACKAGE[pname]
        assert (type(path) == "string", format ("package.%s must be a string", 
pname))
        for c in gfind (path, "[^;]+") do
                c = gsub (c, "%"..LUA_PATH_MARK, name)
                local f = io.open (c)
                if f then
                        f:close ()
                        return c
                end
        end
        return nil -- not found
end
