compiling amaya on netbsd

Hi everyone.
I'm trying to build amaya on NetBSD 3.1.
.../configure is ok.
make gives :

1°) a first error with could not find .depends ( line 40 ).
"""make: 
"/home/david/Desktop/Amaya9.55/Amaya/wx/tools/cextract-1.7/Makefile" 
line 40: Could not find .depends
make: Fatal errors encountered -- cannot continue
make: stopped in 
/home/david/Desktop/Amaya9.55/Amaya/wx/tools/cextract-1.7"""
It doesn't stop, though.

2°) a second error that make everything stops.
"""make: "/home/david/Desktop/Amaya9.55/Amaya/wx/thotlib/Makefile" line 
66: Could not find .depends
make: Fatal errors encountered -- cannot continue
make: stopped in /home/david/Desktop/Amaya9.55/Amaya/wx/thotlib"""

Does someone have an idea why and how to solve it ? I would like to 
suggest an update in the pkgsrc framework.
Thanks.
David Aubril.
