Ah. Thanks Duncan. That makes sense based on some other messages I caught a glimpse of as we tried some things. I will investigate down this line.

Often R is installed by an administrator, and users can't write to the main library, so when they install packages they go somewhere else.  If "somewhere else" isn't first in .libPaths(), R won't see the new installs.
