I wanted to give Dart and Dart Editor a try. I was not able to launch a sample application because Dartium seems to be linked against libbz2.so.1.0. My Fedora installation only has libbz2.so.1. Setting a simple symlink increased the chance that Dart will be further explored by me.
$ sudo ln -s /lib64/libbz2.so.1 /lib64/libbz2.so.1.0
