Upgrading 3.0.10 -> 3.2.1: "Couldn't find schema file for Pg"

I’m in the middle of upgrading RT 3.0.10 to 3.2.1 on OS X using
PostgreSQL 7.4.3, and I encountered an error or warning message.

$ sudo /usr/local/rt3/sbin/rt-setup-database --action schema --datadir
etc/upgrade/3.1.15 --dba postgres

Creating database schema.
Couldn’t find schema file for Pg

I’m assuming this is benign?
