Where have you built llvm? The enable-llvm dir should point to where
you built llvm.

You have to build both a release build of LLVM and llvm-gcc or both
debug. You can't mix. So if you did --enable-checking that Debug. SVN
by default is debug. A release of LLVM is release by default. I think
--enable-optimized and ENABLE_OPTIMIZED=1 are the same, so you should
be ok.

I'm guessing its your --enable-llvm setting.
Hope that helps..
