euca2ools does not correctly specify port when $http_proxy is set

Binary package hint: euca2ools

when http_proxy is set, euca2ools commands send the request via the proxy. However they do not set the port header, and as a result the proxy will forward the request to port 80, not port 8773. The symptom of this is:
$ euca-describe-volumes
Warning: failed to parse error message from AWS: <unknown>:1:49: syntax error
Traceback (most recent call last):

    parser.Parse(string, True)
xml.parsers.expat.ExpatError: syntax error: line 1, column 49

euca2ools could correct this by either using CONNECT when a proxy is set and a ssl session is desired, passing the port when a proxy is set and no ssl session is desired, or by forcing http_proxy off for all their commands (but this may prevent them working behind a firewall).
