 This is because the function is only available in 64bit ruby where int !=
 long.  vim handles this by checking macros that are set at configure time
 rather than build time:

 # if VIM_SIZEOF_INT < VIM_SIZEOF_LONG /* 64 bits only */
 #  if defined(DYNAMIC_RUBY_VER) && DYNAMIC_RUBY_VER <= 18
 #   define rb_fix2int                   dll_rb_fix2int
 #   define rb_num2int                   dll_rb_num2int
 #  endif
 #  define rb_num2uint                   dll_rb_num2uint
 # endif

 I suggest vim use muniversal to address this
