I usually do something like this with poudriere
Touch /tmp/apache25 && tail -f /tmp/apache25 | grep - i "x11"
Then
Poudriere testport jail ports_tree xxx/apache25 |& tee /tmp/apache25

Then poudriere will list the depends and that will get you a list of
depends.

I had to do something like that to find out why certain ports were pulling
in GCC.
