below result rake make command

➜  command-t git:(master) rake make /home/vagrant/.rvm/rubies/ruby-2.2.2/bin/ruby extconf.rb checking float.h... yes checking ruby.h... yes checking stdlib.h... yes checking string.h... yes checking fcntl.h... yes checking stdint.h... yes checking sys/errno.h... yes checking sys/socket.h... yes checking ruby/st.h... yes checking st.h... yes checking pthread_create() in -lpthread... yes creating makefile compiling watchman.c  compiling ext.c compiling match.c compiling matcher.c linking shared-object ext.so 

as mentioned here, need must build against same version used vim.

i think easiest solution rebuilding plugin ruby-1.9.3-p484. prepend path installation $path, check version ruby -v , reinstall plugin.
