Mike, thanks for this tool. I want to use it to introduce ClojureScript to some local JavaScript devs, since they would be less likely to install anything that required the JVM. I cannot seem to get `brew install planck` to work, however. It just hangs. It looks like `brew upgrade` hangs indefinitely as well, though, so this may just be my mac's fault. If anyone knows how to fix this, please let me know.
