Error IOTypes OSTypes not found

I am using Theos and when I use Make Package I get the error:

In file included from /Users/jordan/welcomer/theos/include/IOKit/IOKitLib.h:49:
/Users/jordan/welcomer/theos/include/IOKit/IOTypes.h:56:10: fatal error: 
      'libkern/OSTypes.h' file not found
#include <libkern/OSTypes.h>
     ^
1 error generated.
make[2]: *** [obj/Tweak.xm.fe4c9a81.o] Error 1
make[1]: *** [internal-library-all_] Error 2
make: *** [Welcomer.all.tweak.variables] Error 2

      

        
        
        
      

    

I checked and the OSTypes.h file exists in the libkern folder. I am using rpetrich iPhone headers from his github.

Terminal:
