Comment 5 for bug 1576471

I had a look on why this link points to the wrong target on ubuntu. In their infinite wisdom, the Ubuntu maintainer for the raphael javascript library decided to change the name of the minified script file, breaking the symbolic link. Slow clap.

The fix is easy, make Ubuntu specific version of the package with a symlink that points to the correct filename. I don't have an Ubuntu installation ready for doing this work, so maybe someone will step up and do it. If you need help with it, you can ask me.
