  I would start with making sure the versions of Lua are the same on both
systems.  And for "same version" 5.1.0 and 5.1.5 would be considered "the
same version" for all intended purposes.

  Also, ctrace only works for Lua versions 4.0 to 5.2, but the module needs
to be compiled with the proper version of Lua (which relates to making sure
what versions of Lua you are using).
