Installing mgo for OSX Mavericks

Download Bazaar for OSX via one of the application bundles they have: http://wiki.bazaar.canonical.com/MacOSXDownloads#Application_Bundles

CTRL + double click the .dmg to install it as OSX will not trust the download if you attempt to install it normally.

Now, if you attempt to run go get labix.org/v2/mgo you may find an error regarding some issue with a Python related env variable. Therefore...

Add /usr/local/bin/bzr to your PYTHONPATH env variable

Edit /usr/local/bin/bzr and change the first line #!/usr/bin/python to #!/usr/bin/python2.6

go get labix.org/v2/mgo should now work fine
