无法在Mac OS X 10.6.7上编译Go语言

Question

When following instructions on Getting Started - The Go Programming Language, I get the code and try to run the all.bash script.

But I get this error after a lot of other successful looking output:

Has anybody else seen this and fixed it?

I am running Snow Leopard (10.6.7) build 10J869.

It's an open issue, relating to a new version of Xcode, for OS X 10.7 and 10.6.7.

Issue 1881: cgo const error on OS X 10.7

NOTE: Revision 142f0bc0d6e7 has been made to close issue 1881. To update Go for all changes up to and including this revision, run:

$ cd $GOROOT/src
$ hg pull
$ hg update 142f0bc0d6e7
$ ./all.bash
