>Description:
While updating packages with pkg_rolling-replace on
NetBSD/i386-5.2_STABLE (w/modular Xorg), the build of
"emulators/dosbox" failed as follows:

To double-check, I also tried to build it on NetBSD/i386-current
(6.99.28 as noted in the 'uname -a' output above) and the failure is
the same, although with slightly different compiler arguments:

As I suspect the bulk builds on NetBSD/i386-5.1 are strictly using
native Xorg, "emulators/dosbox" is probably never attempted due to
failed dependencies (i.e. MesaLib).

There was no problem building "emulators/dosbox" on 5.2_STABLE
(again, w/modular Xorg), 6.1_STABLE, or -HEAD throughout the
pkgsrc-2013Q3 branch.

The bulk builds on NetBSD/i386-6.0 show that "emulators/dosbox"
fails to build there as well, but apparently succeeds on
NetBSD/amd64-6.0

Since "dosbox" is host-cpu-independent, I will try building it on
NetBSD/macppc-current soon just to see if there's anything odd.
>How-To-Repeat:
On NetBSD/i386-5.2_STABLE w/modular Xorg or NetBSD/i386-current (native
Xorg), and NetBSD/i386-6.x (according to build build reports), attempt to
build "emulators/dosbox".
