[Ipopt] help building Matlab interface for Ipopt on Mac

[Ray Zimmerman]

Oops missed one tiny thing in step 9. For the 32-bit build, you also need to add a '-maci' in the MEXFLAGS in the Makefile for the MatlabInterface.

I'm starting to think maybe there's an issue with my Fortran compiler since I can't even link the simple yprime example MEX file without getting errors related to -lgfortran.

I had a working setup with both g95 and gfortran (both from Fink) on a previous machine, but decided to go with what I thought was the more highly recommended Fortran installers from http://r.research.att.com/tools/. Now I can't the most basic MEX build to work.
