Go环境搭建(CentOS6.2 i386)

我的环境:
VMware 7.1
OS:CentOS6.2 i386(本来在5.7下，死活过不了所有go的test,到os/exec时出错，没解决)
Go v1
参考文章:
yum:

补充二点:
sudo easy_install mercurial时，报错：
error: Setup script exited with Python headers are required to build Mercurial
于是google，找到这个：
http://d.hatena.ne.jp/ychubachi+tech/20110516/1305521214
运行:
yum install python-devel
再sudo easy_install mercurial就OK了


在运行:
hg clone -r release https://go.googlecode.com/hg/ go
这条命令时，第一次到显示“adding changesets”，然后没反应了，等了10来分钟
然后ctrl+c，再次运行，这下没任何提示了。。。也反应。。。像假死
无奈，关机:
shutdown -h now
然后重新开机，重新运行:
hg clone -r release https://go.googlecode.com/hg/ go
OK了！

另好像go v1已经不用8g或6g之类的命令编译了，他在安装时会自动检测到你是啥(8g或6g还是5g)
然后编译时用go build hello.go即可，他会自动根据环境变量调用对应(8g或6g)的来编译
反正我是没找到8g这个命令的，运行8g报找不到这个命令
以上仅是个人猜测，没有在官方找到文档，有找到的吱一声，谢谢了


附在5.7下运行all.bash的报错:(后换os成6.2就过了)
