I helped with the pkgsrc on BSD/OS.

I no longer have any BSD/OS machines using pkgsrc.

I do still have multiple customers who run BSD/OS in production, but not 
using pkgsrc there.

I don't think anyone else had done anything with pkgsrc on BSD/OS for at 
least a couple years.

It might be useful to keep listed for one reason -- to convert BSD/OS 
users to NetBSD :)
