Comment(by lukexi):

 Seems related to:
 http://hackage.haskell.org/trac/ghc/ticket/2979 (which explains why it
 works with 7.6.1)

 I fixed it by cabal unpacking, and swapping lines 615-622 with those from
 unix-2.5.1.1 in System/Posix/Signals.hsc:
 foreign import ccall unsafe "__hscore_sigdelset"
   c_sigdelset   :: Ptr CSigset -> CInt -> IO CInt

 foreign import ccall unsafe "__hscore_sigfillset"
   c_sigfillset  :: Ptr CSigset -> IO CInt

 foreign import ccall unsafe "__hscore_sigismember"
   c_sigismember :: Ptr CSigset -> CInt -> IO CInt

 and cabal installing.
