Can’t build dependencies on Ubuntu 14.04

```
The following packages have unmet dependencies:
libappindicator3-dev : Depends: libdbusmenu-glib-dev (>= 0.1.8) but it is not going to be installed
libgtk-3-dev : Depends: libpango1.0-dev (>= 1.32.4) but it is not going to be installed
Depends: libcairo2-dev (>= 1.13.0~20140204) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

```

Any suggestions?

Start by reproducing the dependency installation failure on Ubuntu 14.04 using the package list and errors in the issue. Determine whether the project’s dependency instructions or package requirements need updating; done means the dependencies install and the project builds successfully.
