I forget again: is there an easy way to tell if any
ports depend on those?
yes, there is:
$grep :cairo-devel */*/Portfile
I'll put this in the FAQ. Would it be useful to make the port
command do
this in a future revision?

I've put together a script to search for dependents. Here's what it
does:
* works on ports that aren't currently installed
* supports both the (bin|lib):foo:name and the port:name syntax
* matches the exact name [1]
(searching for ncurses does not bring up results for ncursesw)
* supports regexp [2]
(e.g. searching for "ncursesw?")
* finds dependencies that hide in variants
* finds dependencies that hide in comments (yet to be gotten rid of)
setup: the script needs to be run from within the dports folder.
invocation: foo.sh ncursesw?
==== foo ====
#! /bin/sh
# room for customization
SED=/usr/bin/sed
GREP=/usr/bin/grep
$GREP -E "(port|(lib|bin):[^:]+):$1([\t ]|$)" */*/Portfile | $SED "s=/
Portfile:.*==g"
