The pl above will not show errors if there is errors like doucment already indexed or reasons why phpdig does not completely index sites according to your config file they will not show with this pl.
Its shows finished indexing when the spider.php is finished with the url reguardless of what the spider did.
On thing you can do to test the script is run this commmand php -f /path/to/admin/spider.php
http://www.somedomain.com
If the results are good then the script should be working fine.
Just for referance I am currently indexing 1 level and 1 link. and it takes average of 30 seconds to complete one site.
Thanks
