Does anybody successfully built latest R on AIX 5.3?

I am trying to install
http://www.oss4aix.org/download/RPMS/gcc/gcc-4.2.4-2.aix5.3.ppc.rpm

but it dependents on package info, which I can't find a version for
AIX 5.3, can anyone who success fully built R on AIX 5.3 share which
version of gcc and the related packages to use, and where to download
them,thanks, following are the error messages:

# rpm -i ./libgcc-4.2.4-2.aix5.3.ppc.rpm
package libgcc-4.2.4-2 is already installed
# rpm -i ./gcc-4.2.4-2.aix5.3.ppc.rpm
error: failed dependencies:

error: ./info-4.13a-2.aix5.1.ppc.rpm does not appear to be a RPM package
