I have not tried to compile on R2014b yet.
There is a new beta version of the toolbox available at https://github.com/ecoetzee/Dynamical-Systems-Toolbox-V3. This should solve some of the problems below.
Edit to below:
I tried running some examples like Peter and got the same Error:
Error using auto/runauto (line 27)
Could not find appropriate AUTO07gateway mex file for this platform
However I am not using a MAC. Seems to be a general problem.
