Jarkko,
Just encountered this problem myself. Here is the fix, in ~/www/doc/sql/bboard.sql:
create table bboard (
change this:
fips_county_code char(5) references counties,
into:
fips_county_code varchar(5) references counties,
and then bboard db table would be loaded correctly.
hope this help, though a bit late.
Sincerely,
