devel/py-pbr spends time on build (PR#264363)

Hi python developers.

When I made a new port, devel/py-jschema_to_python [PR#264362],

I noticed that I spend time during build [PR#264363].

[PR#264362] https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264362
[PR#264363] https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264363

So I researched this issue like following, I noticed that python run

'git --git-dir=/usr/ports/.git'.

I think that py-pbr requires git on runtime, but...

I don't have any idea to fix this issue,  what I should fix my port or

not, so please help me.
