 > If we cannot reproduce the problem, we need your input what would be
 different on your system that is causing the problem. For example, did you
 ever make any changes to your macports.conf? Setting
 `macosx_deployment_target` in macports.conf would be something that could
 cause this.

 OK, I tried to compile darktable. They say, one need to change some
 options
 ("https://redmine.darktable.org/projects/darktable/wiki/Darktable_on_OS_X"):

 Add to /opt/local/etc/macports/variants.conf
 {{{
 +no_gnome +no_x11 +quartz -x11 +llvm34 +gtk3
 }}}

 Add to /opt/local/etc/macports/macports.conf
 {{{
 buildfromsource always
 cxx_stdlib libc++
 macosx_deployment_target 10.9
 }}}

 Thanks to your hint with `macosx_deployment_target`, I commented that line
 and it passes. :)

 I'm not in that macports building processes, but should the darktable
 build process use the cleaner way to set those options by the/a makefile?
