Ok - the only way I could get it to work was to

a) Install the patch to the source as per the other post from Russia - Thanks.
b) Purchase and install the Intel-mpi v 5.

Running on an Intel Core-7 the NACA0012 example took 36.7 seconds to complete and then running the same .cfg file but with with n 4 it took 14.9 seconds.

Summary -
1. Download from SU2 github -> then
2. Install the Intel MPI
3. ./configure --with-MPI=/opt/intel/impi/

4. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/intel/impi/

5.edit the .bashrc as per example below
# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc

# Uncomment the following line if you don't like systemctl's auto-paging feature:

export SU2_RUN="/usr/local/bin"
export SU2_HOME="/home/hdavidson/SU2"
export PATH=$PATH:$SU2_RUN

6. make
7. as Root - Make install
8. Then run your solve nice and fast.
