No, it's configure && build && test && install, for each project. I 
think we also had discussed this before. coinbrew was supposed to call 
the make install with sudo if $prefix was not writable.
Since the travis jobs are working, I thought that coinbrew indeed 
installs a dependency before building the next one.
