Oops, should be fixed with f03e711 (I thought I had rebuilt the world
after my changes yesterday, but apparently not; sorry about that.)

The issue is that libsigsegv was a =E2=80=9Cmultiple-output derivation=E2=
=80=9D=E2=80=93i.e., it
produced two directories in the store.  However, with commit a06a99f
changed the semantics of the =E2=80=9Clib=E2=80=9D output to be libraries +=
 headers;
libsigsegv has nothing else to install, so its =E2=80=9Cout=E2=80=9D output=
 remained
empty, hence the failure.

Thanks!
