     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.2.0
 Keywords:              |       Port:  luarocks
------------------------+--------------------------------
 LuaRocks code is installed to /opt/local/share/lua/5.2, but it looks it up
 in /5.1.

 Lua 5.2 it is a different language, not fully compatible with 5.1. It
 should not be treated as a package upgrade.

 Lua 5.2 at this moment lacks widespread module support of 5.1. One should
 be able to keep both versions of the language in the system.
