There are a few builds of some forks of CraftBukkit on Github that have support for 1.5_02, including EvilSeph's Github. You can probably expect to see a release soon. https://github.com/EvilSeph/CraftBukkit/tree/ Btw, this does not mean (in any way) that it's going to be fast. It just means someone is starting somewhere.
that unofficial version had backdoors in it that the releaser used to crash 100s of servers...just wait for the official release
