Michael,

I have made considerable progress, but I'm stuck. The vboxadd script is creating 
the links correctly; however, 3D acceleration is not working.

One thing that bothers me is that once ldconfig is run, there are two additional 
links created. The contents of /var/lib/VBoxGuestAdditions/lib is as follows:

finger at linux-utfd:~> ls -l /var/lib/VBoxGuestAdditions/lib/
lrwxrwxrwx 1 root root 34 Feb 22 00:28 libEGL.so.1 -> 
/opt/VBoxGuestAdditions/VBoxEGL.so
lrwxrwxrwx 1 root root 34 Feb 22 00:28 libGL.so.1 -> 
/opt/VBoxGuestAdditions/VBoxOGL.so
lrwxrwxrwx 1 root root 11 Feb 22 00:28 VBoxEGL.so -> libEGL.so.1
lrwxrwxrwx 1 root root 10 Feb 22 00:28 VBoxOGL.so.1 -> libGL.so.1

I think those last two are messing up the library loading. Any ideas on what 
might be wrong?

Thanks,

Larry
