The percolation of errors upward in the load process could drop errors, meaning that a build tree could, depending on the processing order, import the same directory as both "p/vendor/x" and as "x". That's not supposed to be allowed. But then, worse, the build would generate two jobs for building that directory, which would use the same work space and overwrite each other's files, leading to very strange failures. Two fixes: 1. Fix the propagation of errors upward (prefer errors over success). 2. Check explicitly for duplicated packages before starting a build. New test for #1. Since #2 can't happen, tested #2 by hand after reverting fix for #1. Fixes #11913.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
