means that in the templates directory of the course someone set up links pointing to subdirectories of the OPL. E.g. ausLibrary was a link pointing to ASU-topics, etc. When you see
Library/ASU-topics/setAntiderivatives/6-1-47.pg, 1, -1
"Library" is a link pointing to the top level of the OPL and is what we recommend people always do. Using other links is optional and can lead to problems if people don't understand how things are set up. You have two options:
(1) put the links (asuLibrary, etc) back in the templates directory
(2) change the paths so you don't have this issue again.
See e.g. http://webwork.maa.org/wiki/Installation_Manual_for_2.10_on_Ubuntu_14.04#Install_the_WeBWorK_Problem_Libraries which explains things.
