Undefined symbol "_Unwind_GetIPInfo" on FreeBSD 6.0

[David Pratt]

Hi. I have successfully compiled gcc-4.2 from ports collection and also 
from svn without errors but have encountered this error. Can someone 
provide some advice.

Traceback (most recent call last):
   File "test_PyLucene.py", line 27, in ?
     from PyLucene import *
   File "/usr/local/lib/python2.4/site-packages/PyLucene.py", line 33, in ?
     from _PyLucene import *
ImportError: /usr/local/lib/gcc-4.2.0/libgcj.so.8: Undefined symbol 
"_Unwind_GetIPInfo"

Is libgcj broken for this platform or is there a work around for this. 
Many thanks.

Regards,
David
