Multiple cdef error: attempt to redefine 'timespec' at line 925

[Hiyorimi]

importing ffmpeg.torch as local ffmpeg = require ('ffmpeg.torch') after importing other modules with ffi binding, I get an error:

/home/ubuntu/torch/install/bin/luajit: /home/ubuntu/torch/install/share/lua/5.1/trepl/init.lua:384: /home/ubuntu/torch/install/share/lua/5.1/trepl/init.lua:384: /home/ubuntu/torch/install/share/lua/5.1/ffmpeg.lua:36: attempt to redefine 'timespec' at line 925

Is there any other way to bypass it besides extra lua_state or patching luajit ?
