How to resolve the KLEE installation error? Related to "subprocess.py"

Question

I am installing KLEE with the following instructions from http://klee.github.io/getting-started/

I have come to the Step 04: ./configure --make-llvm-lib

However, when I run the command, the following error shows up:

    INFO:Disabling assertions

        if testBitCodeCompiler(llvmgcc, llvmToolDir):
      File "./configure", line 545, in testBitCodeCompiler
        '-o', bitCodeFileName]
      File "./configure", line 220, in runTool
        output = subprocess.check_output(cmd, stderr=subprocess.STDOUT)
      File "/usr/lib/python2.7/subprocess.py", line 568, in check_output
        process = Popen(stdout=PIPE, *popenargs, **kwargs)
      File "/usr/lib/python2.7/subprocess.py", line 711, in __init__
        errread, errwrite)
      File "/usr/lib/python2.7/subprocess.py", line 1308, in _execute_child
        raise child_exception
    OSError: [Errno 2] No such file or directory

It looks like there is a file missing. However, I am not aware of any file that may be used, since I am unfamiliar to KLEE.

I am using Ubuntu 13.04, and have successfully executed the previous steps. I am very grateful for any suggestions. Thanks!

Problem solved. Due to the incorrect version of llvm-gcc used (x86_64 instead of i386 error)
