I have tried your package in a chroot environment (actually in two, a full ubuntu and a lubuntu), and it doesn't start in neither of them.
Stranegly, the problem seems to be different: in the lubuntu case, it just shows the message with the version and quits. In the full ubuntu, it complains with the message "can't import module sage", but for example, sage -python works fine -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
