It hasn't seen much work in the kaffe tree. The
RELEASE-NOTES from 1.0.7 says:
* PowerPC / Mac OS X

  Tested Version: 1.0.7 (Final)
  Configuration: --with-engine=intrp --with-staticlib
                 --with-staticbin --with-staticvm
  OS Version: 10.1
  Hardware: Apple iBook 500Mhz
  Compiled with: Apple Computer, Inc. version
gcc-934.3, based on
                 gcc version 2.95.2

           (actually, I suspect that the 3 that passed
are false positives,
            I need to check the regression testing
script)

I don't know the status of the current version from
CVS, but it would be interesting to hear about it if
you have some time to check if it works.

First, what version are you running? What engine
(intrp, jit, jit3)? Is that on Darwin/i386? So you
ported kaffe to Darwin/i386, right? Could you post the
patches, please? ;)

Then, could you post the result of make check ? Do all
the regression tests fail in the same way?

It probably means that there is a deadlock on the main
thread. You should configure kaffe with debugging
support enabled, read FAQ/FAQ.debugging and post a
stack trace. Preferably, you should configure it to
use the interpreter engine and post the backtrace from
btInt.

The JanosVM 0.8.0 includes some fixes for
powerpc-darwin and a jit3 port. You should get in
touch with Tim Stack in order to see what needs to be
done to merge that code with the kaffe.org tree. See
http://www.kaffe.org/pipermail/kaffe/2002-July/008662.html
for more information.
