I'm trying to install PyLucene 3.4 on my OS X Leopard system. JCC
compiles and installs just fine, the Java bits of Lucene compile OK (a
few warnings), but the last part of the build fails thusly:

My Makefile settings are:
# Mac OS X 10.5 (32-bit Python 2.5, Java 1.6)
PREFIX_PYTHON=/usr
ANT=ant
PYTHON=$(PREFIX_PYTHON)/bin/python
JCC=$(PYTHON) -m jcc --shared
NUM_FILES=3
I finally figured out that I've got Java 6 before Java 5 in my "Java
Preferences", but that doesn't work because Python is 32-bit and Java 6
is 64-bit. So, on Leopard, be careful to set the Java prefs so that
Java 5 is first before installing PyLucene.
