Should we installed llvm manually?

[uwifi]

It was fixed by:
$brew install llvm@4
$echo "export LLVM_DIR=/usr/local/Cellar/llvm@4/4.0.1/lib/cmake">>~/.zshrc

@heifner can you check with bill (I don't know his github handle) to see if this issue is resolved in eos-noon, If so, we should close this out.

@pacificcode Please verify this is fixed with your changes to the mac build.

After installed llvm@4 and uninstalled llvm v6.0.0, I have to export LLVM_DIR

export LLVM_DIR=/usr/local/opt/llvm\@4/lib/cmake/llvm/

[pacificcode]

@jmiddleton exporting the LLVM_DIR will work but you should not have to do that If brew creates its sym links to /usr/local/bin successfully. If not then this will get you what you need.

brew unlink llvm@4 && brew link --force llvm@4

the eosio_build.sh script also does this for you when installing llvm@4.
