我试图安装rJava软件包（R 3.0.2，Ubuntu 14.04），我得到以下内容：
> install.packages('rJava')
...
checking Java support in R... present:
interpreter : '/usr/bin/java'
archiver : ''
compiler : '/usr/bin/javac'
header prep.: ''
cpp flags : ''

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.
按照说明尽职地告诉我：

FWIW，我是从源代码构建R而不是使用软件包管理器，因为我需要最新版本。我已经尝试（重新）安装openjdk-7-jdk，r-cran-rjava，libnative-platform-jni和libatk-wrapper-java-jni（作为疯狂的猜测），但都无济于事。我需要什么才能让JNI工作？
