Go's continuous build system depends on HTTP trailers for the buildlet interface. Andrew rewrote the makerelease tool to work in terms of Go's builder system (now at x/build/cmd/release), but it previously could only create GCE-based buildlets, which meant x/build/cmd/release couldn't build the release for Darwin. https://golang.org/cl/11901 added support for proxying buildlet connections via the coordinator, but that exposed the fact that httputil.ReverseProxy couldn't proxy Trailers. A fork of that code also wasn't possible because net/http needlessly deleted the "Trailer" response header in the Transport code. This mistake goes back to "release-branch.r56" and earlier but was never noticed because nobody ever uses Trailers, and servers via ResponseWriter never had the ability to even set trailers before this Go 1.5. Note that setting trailers requires pre-declaring (in the response header) which trailers you'll set later (after the response body). Because you could never set them, before this release you could also never proxy them.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
