[GRASSLIST:2841] nviz error

[Daniele Scarselli]

I'm trying to open nviz but after the command: nviz -q I obtain the following 
error.

Adding panels from /usr/local/grass57-10_02_2004/etc/nviz2.2/scripts
Nv_(panels)

    (file "/usr/local/grass57-10_02_2004/bin/nviz" line 16)

Would you please tell me what is my wrong?
thanks
