[freenet-chat] Failed linux install

[Jano]

I went to the freesite, clicked on the 'install' which launched the java
install.

I deselected all plugins, hit next, and in the last install step 7/7 the
message shown is:

Online installation mode
/home/user/fn07/node/bin/setup.sh: 36: java: not found
chmod: cannot access `lib/*': No such file or directory

Then it said 'installation failed' after hitting next.

This computer is ubuntu 8.04, java is installed (and I've run nodes here
before). If I go to some command line and issue 'java', it shows its help as
expected. In the firefox about:config page, java appears correctly installed
and detected.

Ideas?
