A couple more notes:

* you should always use cheia.load("modulename") to load modules --
  that will ensure the wrapper script gets executed, and also, some
  modules won't load properly using cheia.loadmodule() since they use
  a different binary linking convention.  The module wrapper script
  takes care of all that.

* for a temporary work-around, you could do something like (untested):

  function file_exists(fn)
    local handle = io.open(fn)
    if handle then io.close(handle) return true end
    return false
  end

  function my_fileinfo(fn)
    if file_exists(fn) then return fs.fileinfo(fn) end
    return nil
  end
