mail/py-mail-parser and ipaddress

[Andrea Venturoli]

Hello.

I'm trying to port a Python software that uses mail-parser, but I'm 
stuck with a problem.

I build py37-mail-parser with Poudriere and install it in a 11.3 jail.

However, I'm getting the following error:

> # mailparser
> Traceback (most recent call last):
>   File "/usr/local/bin/mailparser", line 6, in <module>

AFAICY there is no py37-ipaddress (it should already be included in 
Python 3.7 itself).

I have no idea  whether this is a fault of mine or what.
Any help appreciated.
