Hi.
I believe patch below should fix the build. Here is why changes
are made.
First, is luaL_reg. It was a macro for compatibility with Lua
5.0. It was defined in LuaJIT 2.0 headers, but removed in LuaJIT
2.1. The solution is to use luaL_Reg (note capital R), or to
define the macro again.
Next is removal of "luajit-2.0" substring from the include
directives. LuaJIT 2.0 puts its headers into
/usr/include/luajit-2.0, but since pkg-config files mention
/usr/include/luajit-2.0, it's sufficient to include lua.h without
additional paths. With LuaJIT 2.1 path was changed to luajit-2.1,
that broke the build.
