"Creating a New Revel Application" fails because of unmet dependencies

[rolfedh]

In https://revel.github.io/tutorial/createapp.html, it seems like running myapp fails due to unmet dependencies, as shown below.

• What steps should the user take to prevent these errors?
• Would it make sense to add these steps to tutoria/gettingstarted.md or tutorial/createapp.md?

[rolfedh@fedora-desktop ~]$ export GOPATH="/home/rolfedh/gocode"
[rolfedh@fedora-desktop ~]$ cd $GOPATH
[rolfedh@fedora-desktop gocode]$ ls
bin  myapp  pkg
[rolfedh@fedora-desktop gocode]$ rm -rf myapp/
[rolfedh@fedora-desktop gocode]$ revel new -a myapp
