Simulink don't work on iMac

I have iMac (version late 2009) and operating system is 10.9.4. Matlab is version 2012a Student. I have a problem because Simulink don't work. This is error message:

Making simulation target "untitled_sfun", ...

/Applications/MATLAB_R2012a_Student.app/bin/mex -c -O -DMATLAB_MEX_FILE -I/Applications/MATLAB_R2012a_Student.app/toolbox/stateflow/stateflow/../../../simulink/include -I/Applications/MATLAB_R2012a_Student.app/toolbox/stateflow/stateflow/../../../extern/include -I/Applications/MATLAB_R2012a_Student.app/stateflow/c/mex/include -I/Applications/MATLAB_R2012a_Student.app/stateflow/c/debugger/include untitled_sfun.c /Applications/MATLAB_R2012a_Student.app/bin/mex: line 305: gcc-4.2: command not found /Applications/MATLAB_R2012a_Student.app/bin/mex: line 1326: gcc-4.2: command not found

mex: compile of ' "untitled_sfun.c"' failed.

gmake: * [untitled_sfun.o] Error 1

I have reinstalled Xcode. It won't help.

Xcode no longer includes the gcc compiler that MATLAB is looking for.

See http://www.mathworks.com/matlabcentral/answers/94092-can-i-use-xcode-4-2-to-4-6-as-my-c-or-c-compiler-in-matlab-updated-2013-02-04 for options.
