That is not true. Cairo does get pulled in.

Steps to recreate (on a 10.2 build box):

$ poudriere ports -c -p HEAD
$ poudriere jail -c -v 10.2-RELEASE -j test -p HEAD

just to be safe, I add:

$ echo "OPTIONS_UNSET+= X11" > /usr/local/etc/poudriere.d/test-make.conf

select the one port to build:

$ echo "print/cups" > /usr/local/etc/poudriere.d/test-port-list
$ poudriere options -j test -p HEAD -f /usr/local/etc/poudriere.d/test-port-list

Then do a dry-run:

$ poudriere bulk -n -j test -p HEAD -f /usr/local/etc/poudriere.d/test-port-list

This ends up telling me that the following 126 ports would be built:
