Sorry for the spamming, but here's another error which I believe is
important, trying to get VirtualGL running on Ubuntu/LTSP.
ERROR: ld.so: object 'libdlfaker.so' from LD_PRELOAD cannot be preloaded:
ignored.
ERROR: ld.so: object 'librrfaker.so' from LD_PRELOAD cannot be preloaded:
ignored.
I guess that would be a showstopper, considering these are the libraries
that should be loaded on the server side during login.
