You cannot use gcj/gij to compile Java Lucene sources. You have to use a 
proper, less buggy JDK such as Blackdown's, Sun's or Apple's.
gcj's front-end has too many bugs to compile Lucene from .java sources.

I sure hope this is changing with the new gcj 4.3 in the works that has a 
received a new front-end compiler supporting Java 1.5. But until then, gcj is 
not fit for compiling Java Lucene from .java sources. This is why I'm 
including the pre-compiled Lucene .jar files in the PyLucene source tarballs.

See [1] for more information about compiling PyLucene from trunk with a gcj 
4.x compiler. When you use a gcj 4.x compiler, you cannot use the .jar files 
I produced and uploaded. Why, I don't know, hat's all I know so far. Any 
solution to this mystery is welcome but as it stands, 'make test' fails when 
compiling with these .jar files and gcj 4.x. You must instead produce the jar 
files yourself on that platform, using ant a proper JDK.

If you want this to remain easy, stick with the PyLucene source tarballs and 
with gcj 3.4.6. Otherwise follow the steps in [1] carefully adapting them to 
your platform specifics.
