Hi, Samuel.
>I tried to access the war files from outside the installation using wget, and I get the same error. If I log out from the chroot environment I can download the files using wget. What do I do wrong?
This may be because name resolution wasn't set properly during installation in the container. I believe this was reported before for some of the packages. So right after you install the package and move into container for the first time, but before you run `setup.py`, please check `/etc/resolv.conf` file. It may occur it's empty, or even doesn't exist. So make sure it exists and contains `nameserver 8.8.8.8` entry before you run setup.py. If it will happen to be the case, please follow Zico's suggestion and submit a bug at github. Or let us know, we'll submit it instead.
