newbie needs help building Python 2.5 for Fedora Core 6

[bobmon]

Hello, and please be gentle...

I'm trying to build Python 2.5 on my Fedora Core 6 installation. I
think I've resolved most of my problems, but "make test" reports an
error for test_socket.py, shown below.

I suppose my FC6 installation is missing something, but I have no idea
what. Any ideas, directions, pointers would be most appreciated.

OK, so this fails:

my_ip_addr = socket.gethostbyname(socket.gethostname())

Try it from the python command line. This is what happens when I try it

WOW. I'm gobsmacked...

Try it from the python command line. This is what happens when I try it

Okay, that was interesting...

Apparently there's a subtlety of /etc/hosts that affects this!
Originally it had this line:
127.0.0.1 localhost localhost.localdomain foobar
and I get this result for my machine ("foobar.foodomain.com"): Traceback (most recent call last):

Whe I change /etc/hosts to this:
127.0.0.1 foobar foobar.foodomain.net
localhost.localdomain localhost
Python is happy and I get;

So, problem "fixed" although I have no real understanding of what was
wrong or what's right now.
Only that "gethostbyname()" seems to be really sensitive to the format
of the /etc/hosts file.

Thank you, Tony Nelson.
