Peter,

On a relatively stock 64-bit Ububtu box running lucid, I was able to 
successfully compile rJava with:

sudo apt-get install openjdk-6-jdk
sudo sudo R CMD javareconf
sudo R
 > install.packages("RJava")

Here are the jdk and java packages I have installed:

mrutter at yorick ~> dpkg --get-selections | grep jdk
openjdk-6-jdk					install
openjdk-6-jre					install
openjdk-6-jre-headless				install
openjdk-6-jre-lib				install

mrutter at yorick ~> dpkg --get-selections | grep java
ca-certificates-java				install
java-common					install
libaccess-bridge-java				install
libaccess-bridge-java-jni			install
libbcmail-java					install
libbcmail-java-gcj				install
libbcprov-java					install
libgnuinet-java					install
libgnujaf-java					install
libgnumail-java					install
libitext-java					install
libitext-java-gcj				install
tzdata-java					install

My suggestion would be to remove the other jdk packages and match the 
jdk packages that I have installed and see if that works.
