When backporting the latest Carrot2 for Lucene 2.4.x, apart from the
LuceneDocumentSource (only if you're using it), you'd need to patch the
language model handling code that depends on Lucene:

https://fisheye3.atlassian.com/browse/carrot2/trunk/core/carrot2-util-text/src/org/carrot2/text/linguistic/lucene/SnowballStemmerFactory.java?hb=true
https://fisheye3.atlassian.com/browse/carrot2/trunk/core/carrot2-util-text/src/org/carrot2/text/linguistic/lucene/ChineseTokenizerAdapter.java?hb=true
https://fisheye3.atlassian.com/browse/carrot2/trunk/core/carrot2-util-text/src/org/carrot2/text/linguistic/lucene/ArabicStemmerAdapter.java?hb=true

Take a look at the Carrot2 3.2.0 source code (the
org.carrot2.text.linguistic.* package) for the Lucene 2.4.x implementations
of the above classes.

Cheers,
