[R-SIG-Mac] Change Rscript to 64-bit

[Alton Ing]

Hi Simon

I just installed R 2.15.3 from http://r.research.att.com/ on top of R
2.15.2 from http://cran.r-project.org/bin/macosx/ and both R and
Rscript work in 64-bit mode.

Now RHadoop works perfectly with R 2.15.3 on Mac OS X 10.8 and
hadoop-1.0.4 in pseudo-distributed mode.

Thank you for all your help.

So I have to apologize, I was wrong, it doesn't behave the way it should. We probably want to have Rscript pass the arch on if not set explicitly.
