 What I think is happening is: X11_TYPE=native, and the native library 
 has "png" support, but Pkgsrc does not realise this and does not arrange 
 for libpng to be available as it does for zlib and bzip2.  This causes 
 "fontconfig" to fail at configure time because it detects that "libpng" 
 is not available via pkg-config.
 
 But I'm not sure what the correct solution is.  Possibly unconditionally 
 build-linking png on built-in usage, or possibly adding support to 
 explicitly check for the dependency and conditionally pull it in.  But 
 then perhaps png needs to grow a builtin.mk too...
