There's this Java6 BSD-port, which is running on 32bit-Mac too:
http://landonf.bikemonkey.org/static/soylatte
I tried it yesterday, but I seem to be unable to set it as the default Java version to use when launching the Woopra installer. Even after setting JAVA_HOME and PATH variables (using Terminal and RCEnvironment), the Installer still complains. After tweaking the plist file, the error message now reads:
"Could not launch the application because it requires a version of Java that is not installed.
This application requires Java 1.6 or later, but only the following Java versions are installed: 1.5.0, 1.4.2, 1.5, 1.4. Updating to a newer version of Mac OS X may resolve this."
Some more information (don't know if it's important): I found out that /usr/bin/java is a link to /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java. In /System/Library/Frameworks/JavaVM.framework/Versions, there are subdirectories for all the Java versions - perhaps Soylatte has to be linked here somehow?
I don't know how to solve this problem right now. Perhaps somebody with more experience is able to provide some guidance on how to install the Soylatte 32bit Java6 port.
