>Description:

xulrunner-2.0 (devel/xulrunner), which is depended on by firefox-4.0
(www/firefox), crashes with XFree86 4.5.0 from netbsd-4.
# Why I cannot upgrade X is another story...

The problem is that two versions of libfontconfig (from /usr/X11R6/lib
and pkgsrc) are mixed, and xulrunner crashes mysteriously.
This is caused by the reversed order in RPATH recorded in
xulrunner-bin and libxul.so.
Usually, pkgsrc binaries have /usr/pkg/lib before /usr/X11R6/lib in
RPATH, but the two binaries (xulrunner-bin and libxul.so) have them in
the reverse order for unknown reasons.

These (for example) are normal:
% objdump -x /usr/pkg/lib/libcairo.so | grep RPATH
  RPATH                /usr/pkg/lib:/usr/X11R6/lib
% objdump -x /usr/pkg/lib/xulrunner/libxpcom.so | grep RPATH
  RPATH                /usr/pkg/lib:/usr/X11R6/lib:/usr/pkg/lib/xulrunner

These two have the strange order:
% objdump -x /usr/pkg/lib/xulrunner/xulrunner-bin | grep RPATH
  RPATH                /usr/X11R6/lib:/usr/pkg/lib:/usr/pkg/lib/xulrunner
% objdump -x /usr/pkg/lib/xulrunner/libxul.so | grep RPATH
  RPATH                /usr/X11R6/lib:/usr/pkg/lib:/usr/pkg/lib/xulrunner

>How-To-Repeat:

Install pkgsrc/www/firefox and run it on netbsd-4.

>Fix:

The correct way to fix should be to fix the order in RPATH,
but I do not know how.

I confirmed that Firefox runs without problems if I replaced RPATH in
the two binaries, like this:
sed 
's,/usr/X11R6/lib:/usr/pkg/lib:/usr/pkg/lib/xulrunner,/usr/pkg/lib:/usr/X11R6/lib:/usr/pkg/lib/xulrunner,'
