How do I build a new table on IBM i in RTC using DDL as source?

Want to use DDL as the table definition source, 
Want to have that source under RTC source control.
Can't seem to define a build engine specification that will work.  I've put together a translator using   RUNSQLSTM to pickup the source lib and member, but the build engine doesn't find anything to act against.

Seems like this should be simple, so I'm obviously missing something!  Any pointers would be greatly appreciated.
