O, spoke to soon... It does work. I can see BOTH the Eclipse splash
screens now! Admittedly it crashes soon after that, but this means that
it actually finishes the installation process and tries to actually
start the real application now. Joy!

Attached is the small patch that I made to the source.
And the workspace/.metadata/.log file which shows the errors while
running.

The following is my command line and the console output:

$ BOOTCLASSPATH=plugins/org.apache.xerces_4.0.7/xmlParserAPIs.jar:plugins/org.apache.xerces_4.0.7/xercesImpl.jar ./eclipse -debug
