If I look at the shared X libraries that are in use by Xorg and xterm, I
see some that are shared:

For Firefox it is more difficult to see, since it is a shell script that
uses xulrunner, and a lot of the stuff that it uses is I think loaded
dynamically. But it is based on gtk+.

One thing you can do is to use pkg_comp to set up a separate environment
to build your packages. Inside it you can configure it for modular X.

Hopefully, if you install those client packages but not the Xorg server,
they will use the modular versions of the libraries in /usr/pkgsrc/
instead of the native ones in /usr/X11R7/lib/. But to make sure, the
client-side and server-side libraries should have different names.
(If you don't install native X inside the pkg_comp environment, then
hopefully you can build the modular packages, and I expect that they
won't have /usr/X11R7/lib/ in their library search path. But I haven't
tried that.)
