[LLVMdev] Building libLLVMSupport library - special tricks?

Yes, I'd been pretty much performing the same diagnosis in parallel - it seems we just don't have that libLLVMSupport library built.
Last night, tried the build of clang a few different ways to get that library built - including specifying the --gcc-toolchain option. No Joy!
Which of the clang/llvm source trees provides it? or is it in another source package? tools? Is there a Special Sauce which I must cook up?
(have changed topic title to re-focus on the core issue here!)

llvm-config is supposed to say where the libraries are. Take a look at the
On my system it outputs
-L/usr/local/lib -lrt -ldl -lpthread -lz
and indeed libLLVMSupport is there
$ ls /usr/local/lib/libLLVMSupport*
