This is a good starting point :P

I made a few experiments on a spare PC at work(this is an AMD64 8.0 on
which I was testing ZFS, grat work to all the developers for that).

I reverted your change on the machine, defined WITHOUT_X11 and made sure
all rrdtools dependencies where configured to require the least x11
pieces(cairo requires disabling both xcb and glitz support).

The machine had no ports installed. I ended up with the following ports
installed:

As you can see it already sucked in various things and some fonts. I
tried the tutorial and it works flawlessly in such a setup. I think the
trick is this port: bitstream-vera-1.10_4. If there were some way to
install dejavu without sucking in all of libX11 it would be good too.

could you make your tests without dejavu but with bitstream-vera and see
if it works?

I see pango is depending on x11-fonts/xorg-fonts-truetype, which depends
on some fonts pacjkages but not on libX11.

Hope my feedback helps.
