Dear All, we're trying to implement R on the IBM p690 cluster "Jump" at the research centre in J?lich, Germany (c.f. http://www.fz-juelich.de/nic/Supercomputer/computer-e.html) using the most recent version of R (2.1.0) and precisly following the installation instructions. After ./configure we get the final message: ---------------- R is now configured for powerpc-ibm-aix5.2.0.0
