The environment variable SHLIB_PATH must include the path to the MPE emulator's shared libraries. You can include a path with these Bourne Shell commands:
SHLIB_PATH=$SHLIB_PATH:/opt/mpe/lib export SHLIB_PATH
You can also include a path with this C Shell command:
setenv SHLIB_PATH=$SHLIB_PATH:/opt/mpe/lib
You can add these commands to the each user's .profile or .cshrc start-up file. To make the definition effective for all users, change /etc/profile. Changing /etc/profile requires root privileges.
