From that I see you are using Samba 4.2.14 , is there a possibility of
two smb.conf files or other duplicate Samba binaries ?
Have installed all the required dependencies, see here:

https://wiki.samba.org/index.php/Samba_Dependencies_Required_to_Build_Samba

What is happening is that when winbind is started, it adds the 'BUILTIN'
domain, then the local 'MAIN' domain, it then panics when it tries to
add the AD domain.

All I can suggest is double checking you have all the dependencies
installed to build Samba on gentoo.
