Bugzilla Bug 192733

The imlib-1.9.15-r1 ebuild states a dependency on libX11 that it does not need
itself. Instead, it links to libXext, libSM and libICE, which are not mentioned
therein.

$ readelf -d /usr/lib/libImlib.so

From the configure file:

if test "x$enable_shm" = "xyes"; then
  # Check for the Xext library (needed for XShm extension)
  echo "$as_me:$LINENO: checking for XShmAttach in -lXext" >&5
echo $ECHO_N "checking for XShmAttach in -lXext... $ECHO_C" >&6

and

  # Check for libraries that X11R6 Xt/Xaw programs need.
  ac_save_LDFLAGS=$LDFLAGS
  test -n "$x_libraries" && LDFLAGS="$LDFLAGS -L$x_libraries"
  # SM needs ICE to (dynamically) link under SunOS 4.x (so we have to
  # check for ICE first), but we must link in the order -lSM -lICE or
  # we get undefined symbols.  So assume we have SM if we have ICE.
  # These have to be linked with before -lX11, unlike the other
  # libraries we check for below, so use a different variable.
