If you want to run Antimony on Ubuntu, here is what you will need to do. These instructions are from the Antimony repository here.

1. Install QT 5.4

2. Run:

sudo apt-get install build-essential
sudo apt-get install libpng-dev
sudo apt-get install python3-dev
sudo apt-get install libboost-all-dev
sudo apt-get install libgl1-mesa-dev
sudo apt-get install lemon
sudo apt-get install flex

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9 g++-4.9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9

4. Clone and build Antimony

git clone https://github.com/mkeeter/antimony
cd antimony
mkdir build
cd build

~/Qt5.4.0/5.4/gcc_64/bin/qmake ../sb.pro
make -j8

./app/antimony

5. Run it

make install

I'll be running Antimony on a Mac, and have not tested the Ubuntu install. There are some tips listed at the bottom of the page here that might help if you run in to a road block while trying to build from source. If not, leave a comment and we can try to help!
