If all fails, you can try out what worked for me some time ago:

version go-93dc7f0e302b compiles out-of the box.
Prerequisites:
kernel post-Aug2012
8* suite post-March2012
VERSION file is needed if hg is not installed.
Mercurial is only needed to generate the top-level VERSION file.
You can work around this by creating the file yourself after
pulling the code from the repository.
Either create a fake VERSION file
    echo fake >VERSION
or one that matches what the dist tool would have printed. With sh:
    v=`hg log -r tip --template '+{node|short} {date|date}'`
    echo devel $v >VERSION
Afterwards you can run tar to generate an archive that can
be moved to any system and built without Mercurial.
Cd to go/src and run:
    make.rc
