MATLAB: Trouble Installing libsvm on MacOSX 10.10.5 MATLAB R2013a with XCode7.0.1

libsvmmatlab r2013amex compilerxcode7

Hi there,
I am trying to setup libsvm for mac version of MATLAB R2013a. I have XCode 7.0.1 as C and C++ compiler. I have trouble setting up the libsvm library. I have used the commands as directed in the README file of the MATLAB LIBSVM however I havent got any results. Upon running
mex -setup
I get this result
mex -setup
Options files control which compiler to use, the compiler and link command
    options, and the runtime libraries to link against.
      Using the 'mex -setup' command selects an options file that is
      placed in /Users/OP/.matlab/R2013a and used by default for 'mex'. An options 
      file in the current working directory or specified on the command line 
      overrides the default options file in /Users/OP/.matlab/R2013a.
      To override the default options file, use the 'mex -f' command
      (see 'mex -help' for more information).
The options files available for mex are:
    1: /Applications/MATLAB.app/bin/mexopts.sh : 
        Template Options file for building MEX-files
    0: Exit with no changes
Enter the number of the compiler (0-1):
1
Overwrite /Users/OP/.matlab/R2013a/mexopts.sh ([y]/n)? 
y
/Applications/MATLAB.app/bin/mexopts.sh is being copied to 
/Users/OP/.matlab/R2013a/mexopts.sh

  Warning: The MATLAB C and Fortran API has changed to support MATLAB 
           variables with more than 2^32-1 elements.  In the near future 
           you will be required to update your code to utilize the new 
           API. You can find more information about this at: 
           http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html
           Building with the -largeArrayDims option enables the new API. 
**************************************************************************
I have also configured the Makefile as
MATLABDIR ?= /Users/OP/Applications/MATLAB
Now when I try to run make I get this error
>> make
xcodebuild: error: SDK "macosx10.10" cannot be located.
xcrun: error: unable to find utility "clang", not a developer tool or in PATH
      mex: compile of ' "libsvmread.c"' failed.
If make.m fails, please check README about detailed instructions.
After which I have no idea how to configure this out, So anyhelp is much appreciated.
Many Thanks

See http://www.mathworks.com/matlabcentral/answers/243868-mex-can-t-find-compiler-after-xcode-7-update-r2015b except that you have to change the files to use SDK10.11 rather than SDK10.10 for the new XCode 7.1 release.
