www/reviewboard port and conflict-free Python packages

[Sergey Brunov]

Hello, Python FreeBSD Team!

I would like to ask you to help me with the www/reviewboard 
<https://www.freshports.org/www/reviewboard/> port.
I would like to have the port working well.

Could you please help me to «repair» it?
The port was removed in the scope of this revision 
<https://svnweb.freebsd.org/ports/head/www/reviewboard/?limit_changes=0&pathrev=418056>.

Your help would be greatly appreciated.

Best regards,
Sergey Brunov.
