Have you tried installing IPOPT *without* the MATLAB interface first? The 
installation procedure for the MATLAB interface is considerably more 
difficult (as you no doubt noticed) since you have to compile with the 
correct version of g++, gfortran, etc.

Perhaps the problem is that you are not compiling IPOPT with a C++ 
compiler? Try it with flag CXX=g++ instead of CXX=gcc.
