Hi ! (Sorry for my English, I'm French)

I have two development station :
-one with gentoo linux
-one with ubuntu

I have installed jogl with the following procedure :

1) I've downloaded jogl-2.0-pre-20100907-linux-i586.zip

2) unzipped it in /home/prunkdump/java

3) exported  CLASSPATH=./:/home/prunkdump/java/jogl-2.0-pre-20100907-linux-i586/lib/jogl.all.jar:/home/prunkdump/java/jogl-2.0-pre-20100907-linux-i586/lib/gluegen-rt.jar:/home/prunkdump/java/jogl-2.0-pre-20100907-linux-i586/lib/nativewindow.all.jar:/home/prunkdump/java/jogl-2.0-pre-20100907-linux-i586/lib/newt.all.jar

4) exported LD_LIBRARY_PATH=/home/prunkdump/java/jogl-2.0-pre-20100907-linux-i586/lib

The source code of the second tutorial compile well on the two station (javac SimpleScene.java). But when I launch SimpleScene :

-The program work on gentoo ! with a warning :
libEGL warning: Could not open driver egl_softpipe.so (egl_softpipe.so: cannot open shared object file: No such file or directory)
libEGL warning: The driver can be overridden by setting EGL_DRIVER

-The program doesn't work on ubuntu with this error message :

The two station have exactly the same java and javac version.

An idea ? Where can I search ?
