Problem with samba 4 on Mac OS X 10.5.6

[Piotr Buliński]

Hello,

I have a problem with making samba 4 ( fresh sources from git ) on Mac  
OS X 10.5.6.
I have similar problem like described here:
http://lists.samba.org/archive/samba-technical/2008-October/061670.html

but mine is:
Compiling ../lib/tevent/pytevent.c
Linking bin/python/tevent.dylib
Linking bin/shared/libdcerpc_atsvc.dylib.0.0.1
Undefined symbols:
   "___progname", referenced from:
       ___progname$non_lazy_ptr in heimdal_roken.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

I've tried patching source with patch from:
https://bugzilla.samba.org/show_bug.cgi?id=5412
with combination of function from crt_externs.h in /usr/includes/
There is something like:
extern char ***_NSGetEnviron(void);
extern char **_NSGetProgname(void);

I've tried, but it gives me nothing.

Do you have any idea why it happens?
What is the status of using external heimdal libraries with samba4?
"./configure --help" said that it is experimental,
[--enable-external-heimdal Enable external heimdal libraries  
(experimental,default=no)]
but maybe it could be solution. I don't have idea how to make samba  
with external heimdal, so any help with this will be much appreciated.
