I'll be working on fixing it today. As has been discussed in the past, post llvm/clang-3.8 the configure/automake system was getting stripped out of LLVM and clang. The OS X Xcode build has a legacy step in it that still uses the configure-based build system. I'll be cleaning that up today.</div><div><br></div><div>In the meantime, expect if you use the Xcode build that you'll either need to work with llvm/clang from earlier than yesterday (along with locally undoing any changes in lldb for llvm/clang changes - there was at least one yesterday), or just sit tight a bit.</div><div><br><div>Thanks!</div><span><font color="#888888">-- <br><div><div dir="ltr">-Todd</div></div>
