[lldb-dev] Unable to build lldb 3.5

Our sys admin has been unsuccessful building lldb 3.5 on CentOS 6.5.  We are trying to install it for the first time, because we are compiling software with clang 3.5, and TotalView does not yet support the weird debug info produced by clang.  We hope that 
lldb will do better.

He was unable to build lldb 3.5 with clang 3.5, so he is using gcc 4.8.3, which we are using as the gcc-toolchain for clang builds.  It dies with this error:

      return llvm::sys::DynamicLibrary();

How can we download, build, and install a version of lldb that will debug our clang-3.5-built software on CentOS 6.5?
