My vimrc starts with

lua << EOF
package.path = 
"/local/bernd/lui/?.lua;./?.lua;/local/bernd/lua/lib/?.lua;/usr/lib/lua/5.2/?.lua;/usr/share/lua/5.2/?.lua"
package.cpath="/usr/lib/lua/5.2/?.so;/usr/lib/lua/5.2/?.la;/usr/lib/lua/5.2/?.a"
...

This is the path I use in standalone programs, where everything works fine.

Certainly not, the only Lua I have is 5.2.
