Compiling JOGL?

[pythonlover]

Excuse the obvious newbie question, but I cannot get JOGL to compile.  On Java 1.4.2_03 I get the following error:

generate.c.grammar.glib:
   [antlr] ANTLR Parser Generator   Version 2.7.2   1989-2003 jGuru.com
   [antlr] error: cannot find/copy importVocab file /home/michel/src/jogl/jogl/src/net/java/games/gluegen/cgram/STDCTokenTypes.txt

and then it craps out.  With Java 1.5.0 beta it gets past this point, but then complains that it cannot find some x11 header files later on at, I presume, C++ compilation time.

Anyone seen this before?  I'm trying to do it right, it's probably something obviously stupid on my part.
