Thank you Maxim and Maxime for your detailed review. I considered all of the changes you pointed out, and here are the attatchments of the new patch files. Regarding recursive clone, I packages the runtime dependencies seperately but I left the mruby gems, since they seem to be needed just as source (without needing to be compiled) as they are to be configured by mruby for mruby-zest. I am also not familier with mruby or ruby. Thanks, Sughosha
