63ce882 doc: link to homebrew's troubleshooting page (Gastón I. Silva) Pull request description: A trivial documentation update. When I was following the build steps for mac, I had some errors installing the dependencies. After searching on the Internet, and correcting the errors, I found that `brew doctor` had all the answers I needed. Could have skipped the Internet searches all together. ACKs for top commit: fanquake: ACK 63ce882 - a link to the troubleshooting page seems fine. I wouldn't really want our README to have anything more specific than that.
