Quick Build Problem

Hi - I am new to T2 and want to use it to learn more about Linux. I downloaded the iso file and installed it as per step 1
However, when I try to download the T2 sources for step 2 I get the following message:
"could not resolve hostname 'svn.exactcode.de'.

When I use Opera in my Puppy OS I can access the site.

So far I can not get myself into a situation where I can experience the other problems mentioned! :-)

Can someone please suggest how I can solve this problem?

Thanks
