The problem I met (during liveimage setup) is:
---
# mount -t cd9660 /dev/cd0a /mnt
# cd /mnt/packages
# pkg_add kterm
kterm-6.2.0nb17: setting permissions on /usr/pkg/bin/kterm (o=root, g=wheel, 
m=4511)
# rehash
# kterm
kterm: unable to open font "", trying "fixed"....
 [ mangled font menus etc ]
^C
# setenv XAPPLRESDIR /usr/pkg/lib/X11/app-defaults
# kterm
 [ everything works fine ]

Some packages install app-defaults file into /usr/pkg/lib/X11/app-defaults
but the directory search is handled by X libraries (I guess)
so xpkgwedge doesn't help at run time. (not installed by pkg_add(1))

I had to put setenv XAPPLRESDIR for it, but it took a few hours
to remember it because I completely forgot it. In such case
commented out variable settings in skel files might help users.

Anyway it would be better to add a MESSAGE file that mentions XAPPLRESDIR
to all packages which install app-defaults files (only ancient apps?),
or simply fix our xsrc to search also /usr/pkg/lib/X11/app-defaults
per PR xsrc/26357, as we already added /usr/pkg/bin into the default PATH.
