Thanks!  Yes, it does grow fairly rapidly.

Hrmmm...  IIUC then changing the output from:
#v+
>ctorrent-1.3.4_1::ctorrent-1.3.4_2
>ca-roots-1.1::ca-roots-1.2

#v-

To output like:
#v+
>ctorrent-1.3.4_1::ctorrent-1.3.4_2
>ca-roots-1.1::ca-roots-1.2
>ldconfig_compat-1.0_5::ldconfig_compat-1.0_6

>samba-3.0.21a,1::samba-3.0.21b,1
>w3m-0.5.1_3::w3m-0.5.1_4
#v-

Would satisfy the above requirement.  In other words, any port that has
already been shown would not be shown again.

Ok, so instead of printing:
#v+
>samba-3.0.21a,1::samba-3.0.21b,1
>w3m-0.5.1_3::w3m-0.5.1_4
:>boehm-gc-6.6_1::boehm-gc-6.6_2
::>libtool-1.3.5_1::libtool-1.3.5_2
#v-

The output should be (ignoring samba dependencies):
#v+
>samba-3.0.21a,1::samba-3.0.21b,1
::>libtool-1.3.5_1::libtool-1.3.5_2
:>boehm-gc-6.6_1::boehm-gc-6.6_2
>w3m-0.5.1_3::w3m-0.5.1_4
#v-

To accurately reflect the build order, correct?

It makes sense, assuming that I understand your intent.

Let me know if I do, and if not, then we'll try to reach understanding.
