poudriere: Error: Invalid port origin

[Stefan Bethke]

I'm currently getting:
# poudriere bulk -j 92amd64 -J4 -a 
====>> Creating the reference jail... done
====>> Mounting system devices for 92amd64-default
====>> Mounting ports/packages/distfiles
====>> Mounting ccache from: /poudriere/ccache
====>> Mounting packages from: /poudriere/data/packages/92amd64-default
====>> Logs: /poudriere/data/logs/bulk/92amd64-default/2013-10-11_22h39m00s
====>> Appending to make.conf: /root/diesel/poudriere.d/make.conf
/etc/resolv.conf -> /poudriere/data/build/92amd64-default/ref/etc/resolv.conf
====>> Starting jail 92amd64-default
====>> Calculating ports order and dependencies
====>> Error: Invalid port origin 'net/ngrep-lib' not found.
====>> Cleaning up
====>> Umounting file systems

As that port has apparently indeed be removed, I can understand that ports that might rely on it cannot be built, but why does poudriere abort building any packages?
