[R] JRI problem on 64bit Linux

[Prof Brian Ripley]

Our experience (and that of several others) is that you need Java 1.6 on 
x86_64 Linux for any of the JNI-using R packages to work correctly.  E.g. 
the CRAN check machine is using 1.6.

Please see the posting guide: that asks you to ask the maintainer (who 
knows about the problems).

You need to read config.log: we can't read it for you as it is on your 
machine.
