'which openssl' returns nothing when trying to upgrade OpenSSL

I've been working the last day or so to get openssl upgraded on my machine. I've followed the answers here and here and now I've got some pretty funny results. When I type which openssl I get no response. When I type openssl version I get -bash: openssl: command not found When I type brew install openssl I get Warning: openssl-1.0.1g already installed. Why does brew recognize an installation, but my other terminal commands suggest that nothing is installed? What do I need to do to get my system to recognize the installation that brew is seeing, or what do I need to remove to allow me to do a fresh install of openssl? Edit: 'brew doctor' gives me the following: >Warning: Your XQuartz (2.7.4) is outdated >Please install XQuartz 2.7.5: > https://xquartz.macosforge.org > >Warning: Python is installed at /Library/Frameworks/Python.framework > >Homebrew only supports building against the System-provided Python or a >brewed Python.
