initdb problems

I'm on a RedHat6.1 box.  I've built from RC4 (all sources from
tarball).  Builds/installs just fine, but when trying to do an initdb,
I get this:
[postgres@ioport postgres]$ initdb --pglib=$PWD/lib --pgdata=$PWD/data

We are initializing the database system with username postgres (uid=17).
This user will own all the files and must also own the server process.

Creating template database in /home/postgres/data/base/template1
ERROR:  Error: unknown type 'oidvector'.

ERROR:  Error: unknown type 'oidvector'.

        syntax error 12 : parse errorinitdb: could not create template database
initdb: cleaning up by wiping out /home/postgres/data/base/template1

Perhaps something needs to be looked at before release...
