As it turns out, I was going mad, and it was because I was missing
something.
I had not used an environment variable for the path in so many years I
forgot the priorities, and was assuming that the preferences were
appended to the environment value, not replaced by it. And the problem
showed up because I had set up an environment variable in the global
bashrc to put gpulib in the path for all users.
Thanks a lot, my sanity is restored.
