 Priority:  Normal               |  Milestone:
Component:  ports                |    Version:  2.3.4
 Keywords:                       |       Port:  libevent
---------------------------------+--------------------------------
 libevent's code to detect a broken kqueue implementation on OS X had a bug
 and OS X 10.12 (Sierra) was incorrectly triggering the detection. This was
 fixed in upstream:

 https://github.com/libevent/libevent/commit/df6f99e5b51a3c0786f54cb9822604ec63385400

 Without the above change, programs using libevent and kqueue (like tmux)
 will print the following message on OS X 10.12:

 {{{
 [warn] kq_init: detected broken kqueue; not using.: File exists
 }}}

 I have attached a patch for a new revision of Portfile which incorporates
 the patch above and the patch itself.
