Homebrew Formulas for big boys
For sshpass: brew install https://raw.githubusercontent.com/kadwanev/bigboybrew/master/Library/Formula/sshpass.rb
I have an error when installing sshpass with it expecting gsed rather than sed. To resolve:
cd /usr/local/Library/ENV/4.3
ln -s /usr/local/bin/gsed gsed
brew create --force http://sourceforge.net/projects/sshpass/files/sshpass/1.06/sshpass-1.06.tar.gz
brew install sshpass
./configure --disable-debug --disable-dependency-tracking --disable-silent-rules --prefix=/usr/local/Cellar/sshpass/1.06
make
make install
