Compile cp2k with CUDA on mac osx

[Samuel Lamphier]

All, after a number of modifications, cp2k with CUDA support was
compiled with no errors, however, upon testing I received the
following memory error:

CUDA Error: out of memory
 ASSERTION FAILED:         1.EQ.        0


  stack:
  error in host_mem_alloc_i at line   166 with error type  -1
  message: Could not allocate host pinned memory
    2 error in host_mem_alloc_i at line   166
    1 called from dbcsr_init_lib


 libdbcsr| Abnormal program termination, stopped by process number 6
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 6

Does anyone have any idea what would cause this, I have 2 NVIDIA
quadro 4000 mac pro and 24 GB of ram on the system (MacPro5.1 Snow
Lepord 10.6.8).
