Comment (by kencu):

 The buildbots failed to build `mpv`, but I'm quite puzzled at this moment
 why the build failed on the buildbot.
 <https://build.macports.org/builders/ports-10.6_x86_64_legacy-
 builder/builds/89611/steps/install-port/logs/stdio>. I just built it
 perfectly without issue again on my system.
 {{{
 $ port -v installed mpv
 The following ports are currently installed:
   mpv
 @0.29.1_2+audiocd+dvd+libarchive+network+opengl+osd+python27+rubberband+x11
 (active) platform='darwin 10' archs='x86_64'
 date='2018-12-16T13:25:41-0500'
 }}}

 The error that ends the build is this:
 {{{
 Checking for C plugins                                            : libdl
 not found
 You manually enabled the feature 'cplugins', but the autodetection check
 failed.
 }}}

 The test for this seems to be in `wscript`:
 {{{
    }, {
         'name': 'libdl',
         'desc': 'dynamic loader',
         'func': check_libs(['dl'], check_statement('dlfcn.h', 'dlopen("",
 0)'))
     }, {
         'name': '--cplugins',
         'desc': 'C plugins',
         'deps': 'libdl && !os-win32',
         'func': check_cc(linkflags=['-rdynamic']),
     }, {
 }}}
