dpkg-checkbuilddeps: Unmet build dependencies: liburi-ocaml-dev

This is on my "linaro" branch.

It turned out that liburi-ocaml-dev couldn't be installed because libre-ocaml-dev was being taken from upstream -- which should be ok -- but the upstream package seems to be broken. I worked around this for now in the trusty branch by upgrading our ocaml-re so that it naturally takes precedence. I'll leave this ticket open because we should investigate this a little more and report the bug upstream once we're sure.
