output of cmake -G "Unix Makefiles" ../llvm

Following the instructions on <a href="http://clang.llvm.org/get_started.html">http://clang.llvm.org/get_started.html</a>
I've taken all the steps, even the optional ones, for linux.

At step 7, make fails when trying to link ../../lib/libc++.so because of
undefined references such as:
`__cxa_guard_acquire'

I've attached the (stdout & stderr) output from make using 
`make &> llvm_make_error.txt`

Cmake output seems fine, attached that as well.
