When I try to build sample project "auth_basic" using dub. I get the following error:

Lingwens-MacBook-Pro:authbasic ganlingwen$ dub
Target vibe-d ~master is up to date. Use --force to rebuild.
Building auth-basic-example ~master configuration "application", build type debug.

I am running this code on MAC10.10.4, and have libevent-2.0.22 installed.
Why am I having trouble linking to libevent? I have searched the web, some posts say that I should install libevent-dev instead. However, using brew, I can only install libevent. Is this a known issue or is it just wrong on my laptop?

The installation procedure is as follows:

  1. brew install dub
  2. cd path/to/project
  3. dub
