gmake @4.2.1: Symbol not found: _clock_gettime

[Koersii]

When trying to install ffmpeg with

sudo port install ffmpeg +universal

I get the following error:

--->  Configuring openjpeg
Error: Failed to configure openjpeg: configure failure: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_graphics_openjpeg/openjpeg/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets to report a bug.
Error: Processing of port ffmpeg failed

I installed the command line tools and accepted the Xcode Agreement, cleaned the port with

sudo port clean all

but the error is still there.

So the real error is that gmake is not working:

:info:configure   dyld: lazy symbol binding failed: Symbol not found: _clock_gettime
:info:configure     Referenced from: /opt/local/bin/gmake
:info:configure     Expected in: /usr/lib/libSystem.B.dylib

It looks like this problem can occur if you use Xcode >= 8 on OS X 10.11. See ​https://github.com/tarantool/tarantool/issues/1777 . We don't see this problem with our precompiled binaries because our 10.11 buildbot builder uses Xcode 7.
