EclipseOnPPC64

This is an attempt to describe the steps I took to install a 64-bit Eclipse on a ppc64 machine running Fedora 11 on 04/08/2009:

I should note first that the ppc64 Eclipse bits that I used are not in the Fedora release itself, but are available on koji: http://koji.fedoraproject.org/koji/packageinfo?packageID=183

Download from koji and install either the 64-bit OpenJDK or the 64-bit gcj (the latter should work, though I didn't try it)
Download the five ppc64 Eclipse rpms (pde, platform, jdt, swt, rcp) from koji.
Download and install the icu4j-eclipse rpm for ppc64
Use "sudo yum localinstall eclipse-swt-*.rpm", but notice that some of the dependency packages are ppc rather than ppc64. Don't let yum install them - cancel it!
Install the ppc64 variants of the packages that are shown as ppc. You can do this with "sudo yum install <package_name>.ppc64"
Repeat the sudo yum localinstall on the swt package until all of the remaining package are ppc64 (by luck mostly), and then let yum do those installations.
Repeat the previous three steps on the eclipse-platform, elcipse-rcp, eclipse-pde, and eclipse-jdt rpms.
Use the alternatives command to put the desired 64-bit java in as /usr/bin/java. Or just put the 64-bit java you installed on your PATH ahead of /usr/bin.
Fire up eclipse (just type "eclipse" on the command line)
At this point, Eclipse will complain about a number of missing modules, having to do with gnome themes and such. I used "yum whatprovides" to find the needed rpms, found them either in the local repository on on koji and installed them. This step may not be necessary, but I wasn't sure at the time.
