AIX 7.1, xlc 12.1, python 2.7.6

I build samba with:

./configure --prefix=/usr/local/samba/samba-4.1.4 \
          --sysconfdir=/usr/local/samba/conf --localstatedir=/var/samba/smb \
          --mandir=/usr/local/samba/samba-4.1.4/man --with-privatedir=/usr/local/samba/conf \
          --with-configdir=/usr/local/samba/conf --with-piddir=/var/samba/smb/pids \
          --with-logfilebase=/var/samba/smb/logs --with-acl-support --with-winbind \
          --with-ldap 

make
make install

Trying to start samba gives following error:

# ./RCsamba start
