I get this error when i try to build llvm on my RHEL machine. I have followed the steps, checked out the latest llvm,clang,compiler-rt through svn, and ran configure and make in the build directory. After a while i get the following error.

Hi Appu,

Which version are you building?  If it is after r173465, try reverting
