Problem running CGI - Mailman Admin UI

[Odhiambo Washington]

Hello List Admins,

I am somehow at the end of my thinking capacity with this problem, yet I
think it's something minor that a third eye can help me with:
I have installed mailman-2.1.34 on a brand new box running FreeBSD-12.1.
The problem is that the web UI won't open. It instead prompts me
to download a file. The contents of the file can be seen from the below
link:

<https://pastebin.com/8bh6g6rv>How I have done the installation:
1. I did the manual options
cd mailman-2.1.34
./configure --with-cgi-gid=80 --with-mail-gid=26
make
make install

2. The files in /usr/local/mailman:
drwxrwsr-x  24 root     mailman   1024 Jul 22 17:42 .

What is it that I am being blind to that makes the web UI not open?

Thanking you in advance for being my third eye.
