Requirements:
 * XCode + Command Line Tools
 * Qt5
 * - Qt4 is deprecated
 * autoconf, automake, libtool, net-snmp

Easy install with Homebrew:
 $ brew install autoconf automake libtool net-snmp qt5
 * Beware of buggy macdeployqt in Qt5 > 5.5

Fix permissions
 $ sudo chmod -R u+w /usr/local/Cellar/net-snmp

Add qt to PATH, e.g.
 $ export PATH=/usr/local/Cellar/qt55/5.5.1/bin:$PATH

Clone repository and
 $ cd fwbuilder && chmod +x build_mac.sh && ./build_mac.sh

 $ open fwbuilder.app/
