antlr-2.7.2 under Linux

I'm trying to compile antlr-2.7.2 under Red Hat 7.1 with
j2sdk1.4.2_01. I modified Config.make.in to include CLASSPATH:

: [EMAIL PROTECTED] scripts; diff Config.make.in Config.make.in.bak 
27c27
< ANTLR    = $(JAVA) -cp $(CLASSPATH):$(TOPDIR)/antlrall.jar antlr.Tool
---
> ANTLR    = $(JAVA) -cp $(TOPDIR)/antlrall.jar antlr.Tool
29c29
< ANTLR_BOOTSTRAP = $(JAVA) -cp $(CLASSPATH):@BOOTSTRAP_JAR@ antlr.Tool
---
> ANTLR_BOOTSTRAP = $(JAVA) -cp @BOOTSTRAP_JAR@ antlr.Tool

However after running configure and make I get:


make[4]: Entering directory `/usr/petter/to-cd/antlr-2.7.2/lib/cpp/src'
Building ANTLRUtil.o
In file included from ANTLRUtil.cpp:9:

Have anybody sucessfully built ANTLR 2.7.2 under Linux?  Or is ANTLR
becoming a Windows only distribution?
