Hi Ben and everybody,

I have just built vtp-src-081224 on Slackware 12.2 Linux.
When I start Enviro I have a similar problem to that of Levi Swartzentruber on Nov 20 2008:
"the view is always rotating to the left in a circular motion".
(See his message http://tech.groups.yahoo.com/group/vtp-unix/message/782 ).

Then as soon as I click the Enviro window with the mouse I get a segfault, attached below.
But I don't have a joystick. How to tell Enviro not to look for it?

(This problem was noted in the changelog back in 2006 on 06.09.22
 "Enviro: fixed spinning camera when joystick not found" http://www.vterrain.org/Implementation/ChangeLog/2006.htm  )

I have tried recompiling wxGTK-2.8.4 without a joystick:
../configure --enable-unicode --with-opengl --prefix=/home/dad/wxGTK2.8.4 --disable-joystick
but then Enviro won't compile:

Any thoughts welcome.
