As far as I know, I run strictly native X, and I ran into this in a
freshly created pkg_comp chroot so there shouldn't have been any cruft
from past mistakes lying around.  As I see it, there are two
possibilities: Either fonts/fontconfig is only useful with modular X
and it had no business being built on my native-X system, or
fonts/fontconfig is (potentially) useful with native X.

If pkgsrc fontconfig is not meant to be used with native X, then I'm
perplexed that it got pulled in as a dependency while building
packages for native X.  I think I was trying to build firefox24 when I
first tripped over this, back in April.  However, I've just
successfully built all the packages I care about from a pkgsrc tree
checked out yesterday (2014-06-08) and fontconfig was not required, so
if there was a bug in the dependencies it's gone now.  In this case we
can close the PR.

If pkgsrc fontconfig is expected to build on a native-X system, then we
still have a bug that I can reproduce in a fresh pkg_comp chroot, with
nothing in /etc/mk.conf beyond what pkg_comp puts there itself.  The
bug doesn't affect me personally, but since I can reproduce it
systematically I'm happy to help investigate if anyone else cares about

Is there currently a mechanism for indicating or even enforcing that
certain packages are modular-X-only?  In some cases its obvious, but
for something like fontconfig (whose DESCR explicitly states that it is
independent of X), it's not.
