--- Comment #3 from Karl Relton karllinuxtest.relton@ntlworld.com 2008-01-05 08:08:20 --- Yes - hiding libGL.so enables wineprefixcreate to complete (albeit with an error about not being able to load builtin opengl32.dll because libGL.so is not found - as one would expect).
I'll unhide libGL.so and try wine with +opengl and +wgl and see if I get any more info.
