Is there a way to build Openjdk on a 64-bit Mac OS X 10.6.4?

What about building openjdk for PowerPC 64bit (G5)? Does it take a major
effort with the source to get that done? I got started building with
macports but ran out of disk space, so I'm contemplating if I should
invest any time in it any further.

As I'm on 10.5.8 PPC OpenJDK is my only hope to run a JVM later than
1.5.0_24-149 (java 1.6 and above).

Any advice you can give?
