phpmd uses pdepend. The version in phpmd's composer.json for pdepend is set to : ">=1.1.1" the 2.0.0 version does not appear to work with phpmd 1.5. To fix this I've added the 1.1.* version for pdepend in the company project (MD) and my own project. It would be very nice if this were fixed in the Ibuildings qa-tools.
