I was doing some work for a client and needed to install P4Ruby. This is on AIX5.3.
Turned out to be somewhat of a rigmarole to get GCC installed on the box and in the end I found re-built RPMs at the IBM site. Seeing as how they have obviously removed older versions (e.g. gcc 2.95), thought I would just save copies for posterity here.
Note that as of 2007.2, gcc 3.3.2 was used to build P4API, so that is the version needed for P4Ruby (or similar).
Main site is:
http://www-03.ibm.com/systems/p/os/aix/linux/download.html
That links to gcc 4.0, but if you check the underlying URL, you can go direct to:
http://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/gcc/
Anyway, here are the ones I saved:
