by brainscott:

I'm simply running go build and running into an error on Mavericks.

What is the expected output?
Hello World!

What do you see instead?
# runtime/cgo
clang: warning: argument unused during compilation: '-pthread'
# runtime/cgo
clang: error: no such file or directory: 'libgcc.a'

Which compiler are you using (5g, 6g, 8g, gccgo)?

Not sure

Which operating system are you using?
OSX Mavericks

Which version are you using?  (run 'go version')
go version go1.1.2 darwin/amd64

Please provide any additional information below.

Sadly go 1.1.x will not build on mavericks (with xcode5). I recommend building the
1.2rc5 release instead, or waiting a week til Go 1.2 is released on Dec 1.

Status changed to WaitingForReply.

hg clone -r go1.2rc5 https://code.google.com/p/go
You can also download prebuilt installers and tarballs from the website
