When I tried to add an option i was using "Buildlink methodology" and 
"How to create package from scratch" documents. Does suggested approach 
means new package which is bl3'ed to both asterisk16 and kannel? Doesn't 
it sound overloaded because we need to put downloaded .c in asterisk 
source tree and generally should be compiled inside it?

I commented this out because I tried to use both. What should be used 
when I need to include headers, which are taken not from sources but 
from installed package?

I know, I did it directly for the test.

Thank you, an example may turn to be very handy.

Yes, they do
[root@freon ~]$ ls -la 
/usr/pkgsrc/comms/asterisk16/work/.buildlink/include/kannel/gwlib/gwlib.h
lrwxr-xr-x  1 root  wheel  37 Nov 17 22:54 
/usr/pkgsrc/comms/asterisk16/work/.buildlink/include/kannel/gwlib/gwlib.h 
-> /usr/pkg/include/kannel/gwlib/gwlib.h
[root@freon ~]$ ls -la /usr/pkg/include/kannel/gwlib/gwlib.h
-rw-r--r--  1 root  wheel  4013 Nov 17 21:39 
/usr/pkg/include/kannel/gwlib/gwlib.h

I've tried to search where CFLAGS are located but asterisk seems to be 
extra tough for the beginner.

Snatching at a chance I have one more case to ask about if you don't 
mind. There is a big patch named usecallmanager (usecallmanager.nz) for 
Cisco phones. I believe it may not be a standalone package because it 
patch lot of asterisk source files.

It would be nice to have it as an option but I failed to apply it in any 
automated manner. It is proved working on NetBSD (I applied it manually 
to sources after make patch in pkgsrc).

1. It may not (and I believe shouldn't) be applied via patches/ due to 
multifile nature.
2. I failed to make an option, because we need here to download optional 
patch and patch it before applying.
3. It does not work in localpatches because of different base (running 
in asterisk source tree while localpatches need to run outside of it).

What is the best strategy to make it automatically applying?
