RMNet library missing in Linux

We're running 32-bit AcuCOBOL 9.2.1 for Linux. The RMNET library doesn't seem to have been included. Am I looking in the wrong place?

I would expect to find it in the AcuCOBOL 9.2.1 lib directory, as librmnet.so. But there is no file whose name contains rmnet in that directory.
