An instructor created a problem on a different instance of WeBWork and is moving the pg file over to the instance of WeBWork that I'm supporting.

Below is the error message which indicates a missing file PGunion.pl, which appears to be in the unionLibrary which I have installed. And I've created a symbolic link in the templates directory of the instructor's site. In /opt/webwork/webwork2/conf/global.conf I've aset $webworkDirs{valid_symlinks} = ["/opt/webwork/libraries"];

lrwxrwxrwx 1 webadmin webadmin 36 Dec 18 16:26 unionLibrary -> /opt/webwork/libraries/union_problib

What else to I need to do so that the course sees the path to the union_problib directory?

Thanks.
