I don't have a strong opinion myself, just a desire for us to get
access to better boolops and to get closer to being able to ditch
livarot.

The dependencies might have changed more recently... in addition to
"libcgal10", there is also a "libcgal-qt4-10". On Ubuntu 13.10,
according to Synaptic here are the deps for "libcgal10":

libboost-thread1.53.0
libc6
libgcc1
libgl1-mesa-glx | libgl1
libgmp10
libstdc++6
zlib1g

It's not even recommending or suggesting Qt on that main package. The
changelog doesn't give me any reason to believe it's an Ubuntu
specific change either.

Great, more things to learn that I will likely never have the full
knowledge needed to be able to apply them anywhere. :-)
