OK, I'm really not sure that's worth trying to install these packages as
root. Like I said, the fact that one user found it useful on Linux
doesn't mean it will work for you on OS X.

I think you'd better have a look at R packages in /Library/Frameworks/
and check that Snowball, RWeka and RWekajars files have correct
permissions (particularly the jars/ subdirectories). You should also try
reinstalling these packages, just in case (and check no error messages
are printed).

If it doesn't work, I'll wait for Kurt to step in, as I'm going to waste
your time on silly attempts if I go on. ;-)
