Problem with Mex in Matlab R2012a - Mac OS X 10.8

When I try to mex a file I get the following error. My Mac does have gcc and g++ compilers installed, yet I get these errors.

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

      mex: compile of ' "features_hog.cc"' failed.

Error using mex (line 206)
Unable to complete successfully.*_**

I have copy pasted the following lines from Terminal. These indicate the version of gcc and g++.
