pkgsrc: audio/nas

Greetings!
I have some problem with building nas (Network Audio System) on QNX 6.4.1 with pkgsrc. After bmake and building support
libraries, i have this error on my screen:

[code]configure: creating ./config.status
config.status: creating config.h
config.status: config.h is unchanged
mv -f Makefile Makefile.bak

mv -f Makefile Makefile.bak
bmake: don’t know how to make I. Stop

bmake: stopped in /home/HEAD_641/pkgsrc/audio/nas/work/nas-1.9.1

[/code]
and etc.

What is the I parametr? Any ideas how to solve this problem?
