Hi Stefan,
Thanks for replying!
I have just managed to installed gcc 4.2.4.2 on AIX this evening, and
will try to install gfortran tomorrow, there are a few more questions
great.
1. Are you running R 2.13.0
Currently we are running 2.12.0 (works with both GNU and IBM compilers).
I was not able to compile 2.13 with GNU compilers yet, IBM compilers
work though (are preferable anyway, since performance is higher):

2. Can you share all the environment variables we have to set before running
the configure script.
See the manual and
https://r-forge.r-project.org/scm/viewvc.php/install_scripts/install_R_AIX.sh?view=markup&root=aix
You may download this script (and patches), modify the paths
accordingly, run it (e.g., ./install_R_AIX.sh --ibm for 2.13) and R
should build fine.
There are a couple of notes and patches provided in the R/AIX repository
on R-Forge (e.g., how to get IBM BLAS linked etc., missing third-party
libs installed, etc.).
3. Can you share the full command line of configure script.
see above.
4. According to your experience, is there a huge performance lift compared to
X86 CPUS, what's the clock speed of you Power CPU?
No there isn't. One can use the IBM BLAS library (ESSL), then one will
observe a significant speedup for linear algebra tasks. Note however,
ESSL does not incorporate the full BLAS specification (thus the patch).
In general, R runs slower on the power architecture than on x86.
We have a Power 6 8core CPU @ 3.5 GHz. Actually, we use our system
mainly for memory-demanding applications (<=128GB RAM).
Best,

Subject: Re: [Rd] Does anybody successfully built latest R on AIX 5.3?
We successfully built R on AIX 6.1 but the following instructions should also
work for 5.3.
We mainly used the software from OSS4AIX but also from the "AIX Toolbox for
Linux
Applications" obtainable directly from IBM. Attached you'll find our list of
installed rpms.
This and the instructions provided in the "R Installation and Administration"
manual should
be all you need to build R on AIX systems.
