Comment (by George):

 The error I am getting on rc3 is slightly different than the one in the
 description. Mine is:
 {{{
 Undefined symbols for architecture x86_64:
   "_stg_sel_17_upd_info", referenced from:
       _s1xEL_info in UI.dyn_o
       _s1xG6_info in UI.dyn_o
       _s1xPC_info in UI.dyn_o
       _s1xQ9_info in UI.dyn_o
 ld: symbol(s) not found for architecture x86_64
 clang: error: linker command failed with exit code 1 (use -v to see
 invocation)
 `gcc' failed in phase `Linker'. (Exit code: 1)
 make[1]: *** [ghc/stage2/build/tmp/ghc-stage2] Error 1
 make: *** [all] Error 2
 }}}
 After doing
 {{{
 $ touch ghc/GHCi/UI.hs
 $ make GhcStage2HcOpts='-ddump-to-file -ddump-simpl -ddump-stg -ddump-cmm'
 }}}
 I get:
 {{{

       _s1rNh_info in UI.dyn_o

 Do you still want the UI.dump-{simpl,stg,cmm} files I get at this point?
