Building Bazil generally requires the latest 1.x release of Go.
go get bazil.org/bazil
You'll find an executable in
$GOPATH/bin/bazil. That file is all
that is needed for Bazil itself to run.
To work right, Bazil needs the FUSE utilities installed, specifically
fuse.deb or similar for Linux, and
OSXFUSE for Mac.
sudo apt-get install fuse
Your Linux distribution may require you to add your user account to
fuse, and re-login, to be allowed to use FUSE.
