 Replying to [comment:10 trommler]:
 > As this is a more general issue with the way shared libraries are built
 (see for example trac #7062) and installed in ghc, I did not yet add a
 patch that just fixes the symptom.

 In HEAD linking of shared libraries now has been changed to embed
 RPATH/RUNPATH (see #3072) so I will prepare another patch to embed
 RPATH/RUNPATH for libffi.
