 I see the same thing on oldish current and with pkgsrc HEAD. readelf
 -d on libcairo shows
 
  0x0000000000000001 (NEEDED)             Shared library: [libfreetype.so.6]
  0x0000000000000001 (NEEDED)             Shared library: [libfontconfig.so.2]
 
 and I have
    libfreetype.so.19 in /usr/X11R7/lib
    libfreetype.so.6 in /usr/pkg/lib
    libfontconfig.so.2 in /usr/X11R7/lib
    libfontconfig.so.1 in /usr/pkg/lib
 
 that is, it's linked against pkgsrc libfreetype, but base
 libfontconfig.
 
 The package itself thinks it's using pkgsrc libfontconfig:
    % pkg_info -n cairo | grep fontconfig
    fontconfig>=2.14.1nb1
 
 which is what's supposed to happen; as soon as we're using pkgsrc
 freetype2, everything that depends on it, which means fontconfig, is
 forced to USE_BUILTIN=no.
 
 In cairo itself, I get
 
    % make show-var VARNAME=IS_BUILTIN.fontconfig
    yes
    % make show-var VARNAME=USE_BUILTIN.fontconfig
    no
 
 but...
    % make show-var VARNAME=BUILDLINK_PREFIX.fontconfig
    /usr/X11R7
 
 which is all wrong, and predictably the libraries that are actually
 buildlinked are then the wrong ones. How it got that way, IDK, but
 that's the problem.
 
 Do you see the same thing? I'd expect so...
