Also, for a reason still mysterious to me, if you're building from a PyLucene 
source tarball that contains pre-built lucene jar files, you can only use gcj 
3.4.x. If you're building with gcj 4.x, you must start from svn sources and 
compile the lucene .java files on your machine. The PyLucene Makefile handles 
all that when starting from svn sources.

I've had a sane PyLucene built from gcj 4.1.2 before as well, not just 4.2.0.
