#48015: tmux-devel @20150604-83a7017_0: missing build dependency on pkgconfig
----------------------+------------------------
 Reporter:  larryv@…  |      Owner:  tessarek@…
     Type:  defect    |     Status:  new
 Priority:  Normal    |  Milestone:
Component:  ports     |    Version:  2.3.3
 Keywords:  haspatch  |       Port:  tmux-devel
----------------------+------------------------
 The configure phase fails if `pkgconfig` is not installed or visible. This
 affects our Buildbot buildslaves, and you can observe it for yourself with
 trace mode:

 The error message is misleading; the problem is actually at line 115,
 [https://github.com/tmux/tmux/blob/48a46e066ed2836cf8b58da65a2d730011702ee5/configure.ac#L115
 where configure.ac tries to use PKG_CHECK_MODULES], which is defined in
 `pkgconfig`’s pkg.m4 file.

 I’ve attached two patches. One makes the build use autogen.sh, as upstream
 recommends. It also patches autogen.sh to invoke Autotools verbosely, to
 aid debugging. The other actually adds the dependency on `pkgconfig`.
