Having Open MPI related issues while making CUDA 5.0 samples (Mac OS X ML)

Question

When I\'m trying to make CUDA 5.0 samples an error appears:

Makefile:79: * MPI not found, not building simpleMPI.. Stop.

Answer 1

Or just install using Homebrew. The command is

brew install mpich2

I could compile all the CUDA samples after installing mpich through homebrew.
