Go versions tested:
go version devel +53ebc70d4e9f Sat Nov 01 08:28:09 2014 -0700 linux/amd64
go version go1.3.3 darwin/amd64

It appears there has been a change in the go.net package which prevents compilation on a
number of systems. The break looks like it began at commit b99851978628:

If I clone 0f4b0760c3d0 in the same repository, everything builds as expected.
