 I am experiencing build errors with HEAD. Steps to reproduce:

 {{{
 git clone http://darcs.haskell.org/ghc.git ghc-working
 cd ghc-working/
 ./sync-all get
 perl boot
 ./configure
 make
 }}}

 Build process terminates with an error:

 {{{
 utils/ghc-pkg/Main.hs:881:3:
     No instance for (Bin.Binary (InstalledPackageInfo_ String))
       arising from a use of `writeBinaryFileAtomic'
     Possible fix:
       add an instance declaration for
       (Bin.Binary (InstalledPackageInfo_ String))
     In the first argument of `catchIO', namely
       `writeBinaryFileAtomic
          filename (map convertPackageInfoOut (packages db))'
 ...
 }}}

 I'm using GHC 7.6.2.20130129 for bootstrapping. I'm stuck with development
 because of this :/
