[Samba] samba v4-5-stable build fails

[Cobra Koral]

Hello guys.

I am trying to compile samba from git repository, branch v4-5-stable, and I got this error during ./configure


Checking for perl $Config{vendorprefix}:                                          : '/usr'
PERL_ARCH_INSTALL_DIR:                                                            : '${LIBDIR}/perl5'
PERL_LIB_INSTALL_DIR:                                                             : '${DATADIR}/perl5'

    perl_inc.remove('.')
ValueError: list.remove(x): x not in list

Seems like it is trying to remove a value which is not in the list ?
This happened during PERL environment setup.
So I tried removing the line 52 on the file
    perl_inc.remove('.')

and it just worked.
I haven't installed yet, but as the compile error didn't spit any error, I am guessing the PERL environment was found and compilation worked.

My environment is a GNU/Linux debian 9 testing with nothing else installed, did a netinstall.
I did check https://wiki.samba.org/index.php/Operating_system_requirements/Dependencies_-_Libraries_and_programs
and installed all the dependencies.

Should I open a bug ?
Can someone advise on that please ?

Thanks a lot
