HTTP client&server tests fail. DNS_ServerName and URL_Target strings conjoined into nonsense.

Comment 1 by rsc+personal@swtch.com:

This happens when OS X has the firewall enabled and won't let Go listen on a UDP port 
for the DNS response.  The workaround is either to disable the test (add http and net to 
NOTEST in $GOROOT/src/pkg/Makefile) or disable the firewall.

I get this trying to build on a corporate network.

Comment 3 by twitwad:

Great!  Worked like a charm and the rest of the tests passed.  Thanks!

Comment 4 by ed.crump:

I'm getting something similar.  No firewall.
gopack grc _test/net.a _gotest_.6 
--- FAIL: net.TestDialError
    #2: nil error, want match for `dial tcp no-such-name.google.com.:80: lookup

    #3: nil error, want match for `dial tcp no-such-name.no-such-top-level-domain.:80:
lookup no-such-name.no-such-top-level-domain.( on .*)?: no (.*)`

Comment 5 by cnhackTNT:

to ed.crump:
you should try another DNS, please edit your /etc/resolv.conf or edit your DNS option
via network manager something.

Comment 6 by techknowlust:

I have the firewall disabled yet this problem persists. Is the only other workaround to 
disable testing net and http in the Makefile?

Comment 7:

TestDialError is now disabled by default.
hg pull
hg update release
should get you to a working state.

Status changed to Fixed.

Comment 8 by aaron.blohowiak:

I just pulled and updated, and I am getting a similar error. 
gopack grc _test/http.a _gotest_.6 
--- FAIL: http.TestClient
    Get http://www.google.com/robots.txt: dial tcp www.google.com:http: open /etc/resolv.conf: no such 
file or directory
I do not have an /etc/resolv.conf -- python / bison / ed &c are installed using macports.
The installation *succeeds*, but the tests fail
