Hi Ashok,
I created a new Ubuntu 12.04 virtual machine and followed directions except that I know use your cmake command instead of configure, and I got the error below.
Any help is very much appreciated.

Looks like your make/install is incomplete wrt clang. I follow the
instuctions for checking out the sources but build using cmake instead
of configure:
> cmake -G ""Unix Makefiles" -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_BUILD_TYPE="Release" -DCMAKE_INSTALL_PREFIX="../bin" ../llvm
> make install
This builds and installs llvm+clang in the bin directory one level above
llvm. I tried using configure earlier but had some problems.
