 I must have had libffi installed when I installed ghc
 (6.10.4_0+darwin_9_i386). I later uninstalled libffi via port_cutleaves
 because nothing depended on it. Now, I get this problem when trying to
 build something (alex) that uses ghc:

 {{{
 dyld: Library not loaded: /mp/lib/libffi.5.dylib
   Referenced from: /mp/lib/ghc-6.10.4/runghc
   Reason: image not found
 }}}

 This is similar to #19736.
