[Rd] compile 2.4.1 for linux on power cpus

Thank you for the reply Peter. 

I've compiled R from source using the following:

./configure --host=powerpc64-power5-linux-gnu --build=powerpc64-power5-linux-gnu '--with-blas=-framework blas-3.1.0-11'

and after I've made R I get this:

> .Machine$sizeof.pointer
[1] 4

meanwhile uname -a prints out this:

Linux [hostname] #1 SMP Mon Jul 3 18:25:39 UTC 2006 ppc64 ppc64 ppc64 GNU/Linux

and in the root filesystem there's a /lib and /lib64. I suspect that R needs to have the 64 bit libraries specified so is there a way to do that?

It currently has 12GB of RAM so I'd like to make sure I have the 64 bit version of R so as to take advantage of the extra memory. Since it's a power CPU server that means I'll have to compile R from source.

Just running the 64bit version of the OS usually suffices (at least on 
Linux variants). Easiest check on a running R is

 > .Machine$sizeof.pointer
[1] 4

which gives 8 on 64-bit builds.
