Dependency update fails for leiningen

[tugh]

When I add [vimsical/re-frame-utils "0.1.0"] to project.clj lein deps command fails as below:

$ lein deps
Could not find artifact vimsical:re-frame-utils:jar:0.1.0 in central (https://repo1.maven.org/maven2/)
Could not find artifact vimsical:re-frame-utils:jar:0.1.0 in clojars (https://repo.clojars.org/)
This could be due to a typo in :dependencies, file system permissions, or network issues.
If you are behind a proxy, try setting the 'http_proxy' environment variable.

When I use [re-frame-utils "0.1.0"] instead of [vimsical/re-frame-utils "0.1.0"] everything is fine:

$ lein deps
