In one console:

(w2)d7 192.168.56.101 ~/w2/tmp/weightless-core/weightless/examples % ./httpserver.py

In another console:

d7 192.168.56.101 ~ % curl http://127.0.0.1:8080/
Hello!d7 192.168.56.101 ~ %

It works. Then:

For the problem below, I see you are using GCC 4.7 and Python 2.7 on Linux
3.2. The handling of sockets is usually a bit nifty and depends on the
platform. Therefor I would need to these versions running. I haven't at
the moment, as all my development work is on either Debian of RedHat, which
both lag behind a bit.

However, we will be switching to Debian Wheezy shortly and at that point it
becomes a necessity for us to work, so it will be fixed soon, although I
regret that I cannot do it right-away.
