I have this problem: Applicatio​ns/MATLAB_​R2012a.app​/bin/mex: line 305: llvm-gcc-4.2

Somebody can help me. I have installed matlab2012a and xcode 4.5.2 (4G2008a) in a macbook with mountain lion OS X 10.8.2. When I run the simulink program appears this lines:

/Applications/MATLAB_R2012a.app/bin/mex: line 305: llvm-gcc-4.2: command not found /Applications/MATLAB_R2012a.app/bin/mex: line 1326: llvm-gcc-4.2: command not found

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

gmake: * [Caso_Escalar_sfun.o] Error 1

Thank you!
