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.

# 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.
