Installation of breakdancer by cloning the sourcecode (and subsequent building the code) fails because the submodule "build-common" can't be cloned.
I am following the instruction from the install.MD txt file present in the breakdancer-master.zip file that can be downloaded from the breakdancer github page.
The command I use is : git clone --recursive https://github.com/genome/breakdancer.git
The error I get is :
