Ubuntu 6.10 was the last officially supported PowerPC version of Ubuntu. I don't know what's up with the unofficial Ubuntu PPC builds, but Debian's works fine. If you want to grab a working package, you can take Debian's from: http://packages.debian.org/sid/powerpc/librxtx-java/download
and then do "$ dpkg -i librxtx-java_2.2pre2-8_powerpc.deb" in the directory you downloaded it to. You should be able to install arduino after doing that.
Thanks for the report.
