Ubuntu install feedback
First, great to see this project shaping up. It's a very useful service to the community.
A few things that I ran into when doing the install on Ubuntu (as a new Ubuntu user)
* Only the JRE seems to be available, not the JDK. Having the full JDK available would be very helpful.
* After installing the Sun JVM, it wasn't made the default. Typing "java -version" still resulted in gjc being invoked. Perhaps it's not a best practice to change the default? If that's the case, it would be nice if the documentation discussed how to make the Sun JVM the default, or the installer could provide that as an option.
