problem creating template database

I hope someone can help.  When I use the initdb in postgresql-7.0.2 I get an
error.  It reads as follows:
ERROR: Error: unknown type 'oidvector'.
ERROR: Error: unknown type 'oidvector'.
            syntax error 12 : parse errorinitdb: could not create template
database

I believe the problem is in a field value in the
pgsql/lib/local1_template1.bki.source.  Any help would be great.

Thank you,
