[R] Install R on Mac OS.X

[Tor A Strand]

I am running R 1.8.1 flawlessly on my mac with OS.X.3

My friend is running 1.6.1 but it is impossible for him to make 1.8.1 
work. I do not understand why it should work better in my computer. I 
do, however, have X.11 installed, he doesnt, could that be an issue and 
if it is, does it suffice to install X.11 after RAqua has been 
installed?
