Hi, all.
I install the Xfree from xsrc and set the PREFER_NATIVE=yes in /etc/mk.conf,
then try to build the www/firefox. I find it still install some builtin pkgs
from pkgsrc, e.g.:
% ls /usr/X11R6/lib/libXc*
/usr/X11R6/lib/libXcursor.a             /usr/X11R6/lib/libXcursor.so.1.0
/usr/X11R6/lib/libXcursor.so@           /usr/X11R6/lib/libXcursor_p.a
/usr/X11R6/lib/libXcursor.so.1@         /usr/X11R6/lib/libXcursor_pic.a
% cd /usr/pkgsrc/www/firefox && make clean-depends

Do I misunderstand it's usage?
