Yes, unless you have a specific need to build from source yourself, I would agree that you are better off just using the PPA.

http://www.ethdocs.org/en/latest/ethereum-clients/cpp-ethereum/installing-binaries/linux-ubuntu-ppa.html

Trusty is a bit of a pig for us to build against, because many packages are so old there now, so using OUR binaries will give you a much easier ride.

If you are determined to build from source then all power to you. In that case, please log an issues with all the details against http://github.com/ethereum/webthree-umbrella.
