app_lua fails to install on CentOS due to the following error: + make every-module group_include=klua CC (gcc) [M app_lua.so] app_lua_api.o CC (gcc) [M app_lua.so] app_lua_exp.o CC (gcc) [M app_lua.so] app_lua_mod.o CC (gcc) [M app_lua.so] app_lua_sr.o make[2]: `libkcore.so.1.0' is up to date.

We need a way to properly identify the proper lua lib that needs to be passed during the linking process. Also, on CentOS the lua include files are under /usr/include: # rpm -q --list lua-devel /usr/include/lauxlib.h /usr/include/lua.h /usr/include/lua.hpp /usr/include/luaconf.h /usr/include/lualib.h /usr/lib/liblua.so /usr/lib/pkgconfig/lua.pc As a result, 'DEFS+=-I/usr/include/lua5.1' is not needed on CentOS (having it defined is harmless).
