Hello Bill!
ERROR: ld.so: object '/opt/trinity/lib/kgtk/libkgtk2.so' from LD_PRELOAD
cannot be preloaded (cannot open shared object file): ignored.
Try to unset the LD_PRELOAD environment variable by typing this command:
unset LD_PRELOAD
Most probably it will solve the issue and not break anything else. If it works, then you can make it permanent either by adding this command to some startup file (probably .bashrc or similar) or by finding out where this variable is set and getting rid of it.
Cheers,
