You said you are building on SmartOS, but FWIW on my netbsd-8 system, I have:

ldd on /usr/pkg/bin/mplayer shows 98 libraries including:
        -lutil.7 => /usr/lib/libutil.so.7

and the output order is

/usr/pkg/bin/mplayer:
        -lterminfo.1 => /usr/lib/libterminfo.so.1
        -lc.12 => /usr/lib/libc.so.12

A few suggestions:

  1) save the build output, and grep it for -lutil, libutil, etc.   If you
  can find where in the build it is even trying to look for a library
  named util, that will help a lot.

  2) look at the binary that was produced for mplayer, and use whatever
  tool is appropriate to see if there is anything named util.  (On
  NetBSD this is ldd.)

  3) Look in your entire system with find, after you have built the
  package but before you have deleted the work directory, for anything
  named libutil*, as in
    find / -type f -name libutil\*


I did (1) and did not find util mentioned.  I then looked at the link
line.  The libs part has (extracted and wrapped):

  -L/usr/pkg/lib -L/usr/lib -Wl,-R/usr/lib -Wl,-R/usr/pkg/lib
  -L/usr/pkg/lib/pulseaudio -Wl,-R/usr/pkg/lib/pulseaudio -\
  L/usr/X11R7/lib -Wl,-R/usr/X11R7/lib -L/usr/pkg/lib/ffmpeg4
  -Wl,-R/usr/pkg/lib/ffmpeg4 -fpie -pie
  -ltermcap -lrt -lpng -lz -ljpeg -lgif -lossaudio -Wl,-R/usr/pkg/lib
  --L/usr/pkg/lib -ldvdread Wl,-R/usr/pkg/lib -L/usr/pkg/lib -lfreetype
  --lfontconfig -lfribidi lass -lenca -lz -lbz2 -L/usr/pkg/lib/ffmpeg4
  --lswscale -lswresample lavformat -lavcodec
  --Wl,-rpath,/usr/pkg/lib/ffmpeg4 -lavutil L/usr/pkg/lib/ffmpeg4
  --Wl,-rpath,/usr/pkg/lib/ffmpeg4 -lpostproc lpthread -rdynamic
  --L/usr/pkg/lib -Wl,-R/usr/pkg/lib -L/usr/pkg/lib ldvdnav -lpthread
  --lm -lXext -lX11 -lpthread -lXss -lXv -lXvMC lXvMCW -lvdpau
  --lXinerama -lXxf86vm -lXxf86dga -lSDL -lGL Wl,-R/usr/pkg/lib -lpulse

so I am suspicious of gif especially and somewhat ossaudio.  But I can't
find any reference to libutil in those.   So there is definitely
something funny going on here.
