New description:

 Using ghc straight from the git repository, I just ran sh validate.  The
 ghc that I used to build this new one was  from
 https://github.com/ghcformacosx/ghc-dot-app (a neat packaging of GHC as it
 does not mess with system system files).

 This is on Yosemite DP3, XCode 6 Beta 3.

 {{{
 OVERALL SUMMARY for test run started at Tue Jul  8 21:51:22 2014 BST
  0:45:11 spent to go through
     4039 total tests, which gave rise to
    15863 test cases, of which
    12161 were skipped

       28 had missing libraries
     3606 expected passes
       65 expected failures

        0 caused framework failures

        3 unexpected failures

 Unexpected failures:

 The first two test seem not to be serious:

 Not sure about T5435_dyn_asm

 {{{
