Installing rJava fails consistently, whether installed via
the command line as below, or through "install.packages(
'rJava' )", and whether 0.84 or 0.85 is used, with the
message :-
"checking JNI data types... configure: error: One or more
JNI types differ from the corresponding native type. You may
need to use non-standard compiler flags or a different
compiler in order to fix this."
I've tried to fix it using suggestions from the r-help list,
and the Gentoo java documentation, but had no joy so far.
Other Java stuff works fine on this box.

The compiler mentioned in the R output :-
/home/astaines/.gentoo/java-config-2/current-user-vm
is a link pointing to
/usr/lib/jvm/sun-jdk-1.6
which in turn is a link pointing to
/opt/sun-jdk-1.6.0.20
however, any of the three will work.

JAVA_HOME is unset by default on my system. As suggested, by
Godmar Back, on the list I've tried setting it. The Gentoo
way is to use
JAVA_HOME=$(java-config --jdk-home)
and this produces what I think is the desired result
#printenv | grep -i JAVA_HOME
JAVA_HOME=/opt/sun-jdk-1.6.0.20
BUT
# env JAVA_HOME=/opt/sun-jdk-1.6.0.20/ R CMD javareconf
