Unfortunately, no, it doesn't say anything specific:

No such luck: The appliance doesn't have "ldd", and I couldn't find it
in the buildroot it uses to build the uClinux kernel.

I tried building/using "random" but there's a bug in the script. I
don't know enough about Lua to know what it is:

==========
/var/tmp/random# make
bfin-linux-uclibc-gcc -I/var/tmp/lua-5.1.4/src -O2 -ansi -Wall
-pedantic   -c -o lrandom.o lrandom.c

bfin-linux-uclibc-gcc -shared -o random.so lrandom.o

/var/tmp/lua-5.1.4/src/lua test.lua
/var/tmp/lua-5.1.4/src/lua: 1: Syntax error: "(" unexpected
make: *** [test] Error 2
==========

I wonder if the problem is not in the way I compile Lua, rather than
modules. It's strange that Google doesn't return more infos on that
error.

Thank you.
