newbie question: gdk2/gtkpixbuff install fails

[Oliver Iberien]

I'm trying to repair the damage after some portupgrading. The linux emulation 
is all messed up. linux-realplayer won't run because it wants to reinstall 
gtk-pixbuff, which is already in there but now conflicts with gdk2, which in 
turn seems to have a broken port:

/usr/bin/gtk-query-immodules-2.0-32: error while loading shared libraries: 
libXfixes.so.3: cannot open shared object file: No such file or directory
*** Error code 127

Stop in /usr/ports/x11-toolkits/linux-gtk2.
*** Error code 1

Stop in /usr/ports/x11-toolkits/linux-gtk2.
** Command failed [exit code 1]: /usr/bin/script -qa /tmp/portupgrade1616.0 
make reinstall
egrep: /var/db/pkg/linux-gtk2-2.4.14_3/+CONTENTS: No such file or directory

I can't make any sense out of this one. I can't find anything in the list 
archives. Any clues?

Thanks,

Oliver
