Is there a way to set things up so that I can streamline the install across all the vm's and ensure permissions are set correctly on each vm?

The root squashing is in the exports on the server side.  This maps uid
0 to nobody,
which is why the access is denied.  One solution: make all the files
readable by
other and the directories are readable and executable by other.
However, since this
is generally the default it's not clear why this is happening.  You
didn't show us
the permissions as I asked, so it's not possible to do more than
speculate.  What does
this show (with any typos fixed)?

ls -ld / /home /home/michael.obrien /home/michael.obrien/setups
/home/michael.obrien/setups/OpenCV
/home/michael.obrien/setups/OpenCV/opencv-2.4.12
/home/michael.obrien/setups/OpenCV/opencv-2.4.12/build

I'll hazard a guess that your homedir is 0700 or 0750; if so it'll need
to be 0755 (so that any user can access it, including nobody); likewise
for any other directories which you want root to read.
