Missing library when running AMS in Hybrid mode

When running AMS 5.0.1 Pro in Hybrid mode we are getting an error in the core log that a library is missing.  /opt/ams/modules/scriptengines/libas1.so.  The directory exists with libasc.so and no other libraries.

Where can the missing libas1.so library be found?  Why was it not included in the installer?
