 And this is from my latest test, with newlines manually added for legibility:
 
 [*] /pkg_comp/obj/pkgsrc/fonts/fontconfig/default/.wrapper/bin/libtool
 /pkg_comp/obj/pkgsrc/fonts/fontconfig/default/.wrapper/bin/libtool --silent
 --tag=CC --mode=link gcc -O2 -I/usr/pkg/include -I/usr/include
 -I/usr/X11R7/include/freetype2 -L/usr/pkg/lib -L/usr/lib
 -Wl,-R/usr/lib -L/usr/X11R7/lib -Wl,-R/usr/X11R7/lib
 -Wl,-R/usr/pkg/lib -o fc-cache fc-cache.o ../src/libfontconfig.la
 <.> /usr/pkg/bin/libtool --silent --tag=CC --mode=link gcc -O2
 -I/pkg_comp/obj/pkgsrc/fonts/fontconfig/default/.buildlink/include
 -I/pkg_comp/obj/pkgsrc/fonts/fontconfig/default/.x11-buildlink/include/freetype2
 -L/pkg_comp/obj/pkgsrc/fonts/fontconfig/default/.buildlink/lib
 -L/pkg_comp/obj/pkgsrc/fonts/fontconfig/default/.x11-buildlink/lib
 -Wl,-R/usr/X11R7/lib -Wl,-R/usr/pkg/lib -o fc-cache fc-cache.o
 ../src/libfontconfig.la 
 
 As far as I can see, the only differences are in path prefixes due to
 the use of a separate obj/ directory in pkg_comp.  Inside the chroot,
 x11-links and libtool-base were built Dec. 23rd from a pkgsrc checkout
 a day or two prior.  The base system in the chroot is amd64-current as
 of late February.
 
 I also tried building fontconfig directly in the underlying system
 (NetBSD/amd64 7.99.2), without using pkg_comp.  I still get an
 undefined reference to FcDirCacheRescan.  The relevant lines
 in .work.log look like:
 
 [*] /build/pkgsrc/fonts/fontconfig/work/.wrapper/bin/libtool
 /build/pkgsrc/fonts/fontconfig/work/.wrapper/bin/libtool --silent
 --tag=CC --mode=link gcc -O2 -I/usr/pkg/include -I/usr/include
 -I/usr/X11R7/include/freetype2 -L/usr/pkg/lib -L/usr/lib
 -Wl,-R/usr/lib -L/usr/X11R7/lib -Wl,-R/usr/X11R7/lib
 -Wl,-R/usr/pkg/lib -o fc-cache fc-cache.o ../src/libfontconfig.la
 <.> /usr/pkg/bin/libtool --silent --tag=CC --mode=link gcc -O2
 -I/build/pkgsrc/fonts/fontconfig/work/.buildlink/include
 -I/build/pkgsrc/fonts/fontconfig/work/.x11-buildlink/include/freetype2
 -L/build/pkgsrc/fonts/fontconfig/work/.buildlink/lib
 -L/build/pkgsrc/fonts/fontconfig/work/.x11-buildlink/lib
 -Wl,-R/usr/X11R7/lib -Wl,-R/usr/pkg/lib -o fc-cache
 fc-cache.o ../src/libfontconfig.la
 
 Which still looks equivalent to yours.
 
 I tried running
 
 nm * |grep FcDirCacheRescan
 
 in work/.x11-buildlink/lib , work/.buildlink/lib and /usr/X11R7/lib
 without finding anything.  work/fontconfig-2.11.1/fc-cache/fc-cache.o
 does contain FcDirCacheRescan (again checked using nm). I'm puzzled that
 libtool can't link against that definition, but I'm not familiar with
 it.
 
 It may be worth waiting until I can update my base system (both the
 real one and the sets used to set up the chroot for pkgcomp), since all
 my failed tests have that in common.
