Where is pim6dd and pim6sd in FreeBSD6.1?

[chenxiaochen]

Dear all:
In release note of 5.0R,it is said that pim6dd and pim6sd have been removed due to restrictive licensing conditions. These programs are available in the ports collection as net/pim6dd and net/pim6sd. 
I can find the ports of pim6dd and pim6sd in FreeBSD 5.4, but none in FreeBSD 6.1.
Do you know where is pim6dd and pim6sd in FreeBSD6.1?
				
Best Regards!
