Can you do this:

   sudo -s
   cd /home/michael.obrien/setups/OpenCV/opencv-2.4.13/build

That will check that root has permission to cd there.  One thought for 
why this might fail: is your homedir on NFS with root_squash enabled? 
That might prevent root access.  What are the permissions on this 
directory, and its parents?
