Just for the record/benefit of a future stumbler over this thread, I found the 
problem (my own stupidity, of course, but I mean in more detail...).

This is an app that I've been using and developing for over four years, and 
hence over many versions of Rev (possibly starting in 1.0???) on Mac and 
Windows, but am just now moving to Linux.

In the Standalone Application Settings, there is a checkbox for Database 
Support; and there is also an item "Database" in the list of Script Libraries. 
  It turns out that when building a database to Mac and Windows, if Database 
Support is checked, there is no need to select "Database" in the script 
libraries.  However, the same is not true for Linux...
