Humm. The error simply indicates the user doesn't have the variable in their path. I suspect this is because you are sourcing the setenv.sh file as your user, then running the program as root. Try this instead:

cd build/utests
source setenv.sh
./utest_run

Notice I didn't use sudo when running the unit tests. It should execute fine (although on Haswell you may need to apply the kernel patch for the local memory tests to pass). Also, you may want to check out the `Release_v1.1` branch as this is the most recent stable version.
