Ahh!!!  Thank you.

Just to get this on record and to be able to search and find it - could 
you post the script that does the check against the pkgng database?

If you are downloading the packages from the 'standard' FreeBSD package 
repository it would be useful to be able to see what options they built 
the packages with.
