spamprobe and Berkeley DB

[Ben Gross]

Hello spamprobe port maintainers,

First, thanks for keep the port up to date. Overall, the spamprobe  
port works well. The only issue for me is it has an old berkeley DB  
port, db4 hard coded which is less reliable than the newer Berkeley  
DB ports. If the Berkeley DB selection code could be ripped from  
another port such as www/apache2, security/cyrus-sasl2 or mail/ 
postfix and put in the spamprobe port it would make it much easier to  
use db42 or even db43.

Thanks,
Ben
