I'm trying to install the rJava package (R 3.0.2, Ubuntu 14.04) and I get the following:
> install.packages('rJava')
...
checking Java support in R... present:
interpreter : '/usr/bin/java'

configure: error: One or more Java configuration variables are not set.
Make sure R is configured with full Java support (including JDK). Run
R CMD javareconf
as root to add Java support to R.
Dutifully following the instructions gets me:

FWIW, I built R from source rather than using the package manager because I needed the newest version. I've tried (re)installing openjdk-7-jdk, r-cran-rjava, libnative-platform-jni, and libatk-wrapper-java-jni (as wild guesses), all to no avail. What do I need to get JNI working?
