 We strongly recommend following the instructions for building the public testnet version for [Ubuntu](#autoubuntupublic) or [Mac OS X](#automacpublic). `master` is in pieces on the garage floor while we rebuild this hotrod. This notice will be removed when `master` is usable again. Your patience is appreciated.

+
+To use the WASM compiler, EOS has an external dependency on [binaryen](https://github.com/WebAssembly/binaryen.git):
+
+```bash
+cd ~
+git clone https://github.com/WebAssembly/binaryen.git
+cd ~/binaryen
+git checkout tags/1.37.14
+cmake . && make
+
+```
+
+Add `BINARYEN_ROOT` to your .bash_profile:
+
+```bash
+echo "export BINARYEN_ROOT=~/binaryen" >> ~/.bash_profile
+source ~/.bash_profile
+```
+
+By default LLVM and clang do not include the WASM build target, so you will have to build it yourself:
+
+```bash
+mkdir  ~/wasm-compiler
+cd ~/wasm-compiler
+git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/llvm.git
+cd llvm/tools
+git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/clang.git
