This means that you're loading bit.so from the current directory,
not from where it was installed. Moreover, the bit.so in the current
directory does not seem to be a Lua library.
Make sure LUA_CPATH or package.cpath contain "/usr/local/lib64/lua/5.1/?.so"
before ".".
To avoid surprises like that, we moved "." to the end of the paths in Lua 5.2.
