I set CLASSPATH in ".bashrc" (not ".bash_profile") as

CLASSPATH=.:/usr/share/antlr/lib/antlr.jar
CLASSPATH=$CLASSPATH:/home/edcjones/cvlib/antlr/cgram/grammars
export CLASSPATH

Does the following completely define the process of setting the
CLASSPATH?

     In your ".bashrc" file include the lines:

     CLASSPATH=.:/path-to-antlr.jar-file/antlr.jar
     export CLASSPATH

     Add to the CLASSPATH any directories containing java programs 
     that need to be visible.

     Logout and logon again.

I have noted two things about Gentoo's version of antlr. First, Gentoo
creates a directory /usr/share/antlr/lib containing the three files
     antlr.debug.jar  antlr.jar  antlrall.jar
Second, Gentoo includes a patch named :antlr-2.7.2-gcc3-gentoo.patch":
