ripe whois database install

Hi,
I've got an error when attempt to run make_db script during
ripe-dbase-3.2.0 installation:
./make_db -c /usr/local/whoisd/conf/rip.config.sample -s SAMPLE -1
Error: Non-existent database "SAMPLEDB" referenced !!!
died: +792 ca_sourceLoader.c
************** ERROR ***************
***  18:31:02 unknown source SAMPLE
************************************

I made change in my source.sample file :
DATABASE        SAMPLEDB
host:           localhost
port:           3306
trx_support: n
user:           whois_admin
password:       ********
/DATABASE

Any ideas?

Kind regards.
