initdb failed due to syntax error

I recently downloaded and built Postgresql 7.2.2. In trying to run
the "gmake check" after the build I get an error indicating that
initdb failed. I turned on the debug option so the text below
contains some of the debug statements output from "gmake check". Note
the error at the bottom "ERROR: syntax error at line 2658: unexpected
token parse error". It seems like this is complaining about the
syntax of line 2658 in the postgres.bki file, but I don't see any
problem with the syntax here.

Does anyone have any ideas about the problem here?

Thanks,
Jeff Stevens
