the appropriate version number listed in the Makefile). Then "make

Notes
------
-The name of the daemon is "pl_mom" but the package name is pl_dod.
-The reason is that the daemon and package were both originally called
-pl_dod. Yum (the package management tool currently in use) does
-not seem to honor the "Obsoletes:" tag in the .spec file. Therefore
-it was not possible to automatically update the old pl_dod package
-with a new one called pl_mom, and so the package kept the old name.
