x11-themes/gtk-qt4-engine does not install

[Patrick Lamaizière]

Hello,

x11-themes/gtk-qt4-engine does not install if the option  
"LIBBONOBOUI  Install libbonoboui if missing" is set:

baby-jane:/<1>ports/x11-themes/gtk-qt4-engine# make install
===>  Installing for gtk-qt4-engine-1.1_1                  
[...]
===>   Generating temporary packing list 
usage: mtree [-LPUcdeinqruxw] [-f spec] [-f spec] [-K key] [-k key] [-p
path] [-s seed] [-X excludes] 

*** Error code 1
Stop in /usr/ports/x11-themes/gtk-qt4-engine.


With "make -dA install", mtree fails with the line :
