This is a known bug in OSX. We need to document it (I thought I already did). The thing is the OpenCL compiler does not obey the -Ipath given when building, so any headers needed by the kernel must exist in current directory:
magnum@...r-osx:john [unstable-jumbo]$ run/john -t -fo:agilekeychain-opencl
OpenCL platform 0: Apple, 2 device(s).
Device 1: GeForce GT 650M
Build log: <program source>:15:10: fatal error: 'opencl_device_info.h' file not found
#include "opencl_device_info.h"
^
Error -11 building kernel. DEVICE_INFO=130
OpenCL error (CL_BUILD_PROGRAM_FAILURE) in file (common-opencl.c) at line (209) - (clBuildProgram failed.)
magnum@...r-osx:john [unstable-jumbo]$ cd src
magnum@...r-osx:src [unstable-jumbo]$ ../run/john -t -fo:agilekeychain-opencl

Note that after a succesful build, the kernel binary is cached. So once the successful run-time build is made, you can move away from src:
magnum@...r-osx:src [unstable-jumbo]$ cd ..
magnum@...r-osx:john [unstable-jumbo]$ run/john -t -fo:agilekeychain-opencl
OpenCL platform 0: Apple, 2 device(s).
