For those getting the error:

error: unable to load shared object '/some/dir/rJava/libs/rJava.so': libjvm.so: 
cannot open shared object file: No such file or directory

I solved the error locating the library in the system and linking them to /usr/lib:

$sudo updatedb
$locate libjvm.so
/usr/lib/debug/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/libjvm.so
/usr/lib/debug/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/zero/libjvm.so
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/jamvm/libjvm.so
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/libjvm.so
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/zero/libjvm.so
$sudo ln -s /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/libjvm.so /usr/lib/
