samba - Nov 2004 - Winbind installation on AIX installation woes

I'm new to Samba, and am trying to set up Samba with Winbind on AIX 5.2.
 The machine is running on is a single-processor 1.2Ghz with 2GB of RAM.
 The cc compiler I am using is version 6.0.
 
I downloaded the Samba source and executed the following sequence of
commands:
 
configure --with-winbind
make build
make install
 
These commands do not seem to have built the libnss_winbind.so file
that the instructions claim in the /source/nsswitch directory.
 
My questions are:
 
1) In order to use Samba with winbind, do I need to add any more flags
to my commands above?
 
2) Why didn't the libnss_winbind.so library get built?
 
3) The configure and build step took about a day each to run.  Any
ideas on why it would take such a ludicrously long time?
 
Thank you.
