[Vrmlengine-main] compiling issues

[<da...@la...>]

I have been trying to compile the view3dscene tool from source becouse the 
32 bit packages available don't work on my 64 bit ubuntu install (too many 
dependancies on libraries)

I have some structures that I've created with CAD programs I want to do walkthroughs on

however I am getting permission denied errors when I try to run the 
result. I tried running the tests, but they seem to want a bunch f other 
things available (including the castle game)

any pointers?
